[0041] First, some terms involved in the embodiments of the present disclosure are explained below to facilitate understanding by those skilled in the art.

[0042] LLM (Large Language Model): is an artificial intelligence model designed to understand and generate human language. By training on large amounts of text data, it can perform a wide range of tasks, including text summarization, translation, sentiment analysis, and more. Its characteristic is its large scale, which helps them learn complex patterns in language data.

[0043] Agent: In computer science and artificial intelligence, it refers to an entity or software program that can independently perform tasks, make decisions, and operate autonomously in a specific environment. An agent can be a simple software script or a complex robotic system.

[0044] The foregoing introduces some terms and concepts involved in the embodiments of the present disclosure. The following introduces the technical features involved in the embodiments of the present disclosure.

[0045] With the in-depth development of technologies such as deep learning and large language models, it is possible to migrate the operating system automatically and efficiently. This application is based on such industry background and technology development trend, and aims to provide users with higher migration efficiency and migration success rate by building an efficient and automated operating system migration solution to reduce manual intervention in the operating system migration process.

[0046] Existing system migration methods mainly rely on the manufacturer's tools supplemented by manual operations, which are not universal. In addition, manual methods require manual user configuration and manual script writing, which may subsequently bring compatibility issues such as the kernel, basic software packages, and tool chains, as well as dependencies and data integrity during the migration process.

[0047] In response to the above problems, this application proposes the following technical solutions.

[0048] The exemplary embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0049] Figure 1 A schematic diagram of a scenario that can be applied to a system migration method or a system migration device in an embodiment of the present disclosure is shown.

[0050] Please refer to Figure 1 , which shows a schematic diagram of an implementation environment provided by an exemplary embodiment of the present disclosure.

[0051] like Figure 1 As shown, the system architecture 100 may include terminal devices 101, 102, 103, a network 104 and a server 105. The network 104 is used to provide a medium for communication links between the terminal devices 101, 102, 103 and the server 105. The network 104 may include various connection types, such as wired, wireless communication links or optical fiber cables, etc.

[0052] Users can use terminal devices 101, 102, 103 to interact with server 105 through network 104 to receive or send messages, etc. Terminal devices 101, 102, 103 can be various electronic devices with display screens and supporting web browsing, including but not limited to smart phones, tablet computers, laptop computers, desktop computers, wearable devices, virtual reality devices, smart homes, etc.

[0053] The server 105 may be a server that provides various services, such as a background management server that provides support for devices operated by users using the terminal devices 101, 102, and 103. The background management server may analyze and process the received request data, and feed back the processing results to the terminal device.

[0054] The server can be an independent physical server or a server cluster or distributed system composed of multiple physical servers. It can also be a cloud server that provides cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), as well as basic cloud computing services such as big data and artificial intelligence platforms, etc. The present disclosure does not impose any restrictions on this.

[0055] The above-mentioned agents (such as migration assessment agents, migration transformation agents or migration implementation agents) can be deployed in a single terminal device or a single server, or can be distributedly deployed in terminal devices or servers. This application does not impose any restrictions on this.

[0056] In addition, the above-mentioned migration assessment agent, migration transformation agent or migration implementation agent can be deployed on the same device or on different devices, and this application does not impose any restrictions on this.

[0057] Assuming that the above-mentioned migration assessment agent, migration transformation agent and migration implementation agent are all deployed in the server 105, the server 105 can, for example, use the migration assessment agent to evaluate the compatibility of the target application on the source system with the compilation and running environment on the system to be migrated, the adaptability of the executable file and the adaptability of the configuration, so as to determine the source code transplantation modification content or the configuration modification content of the target application corresponding to the library package or executable file that is incompatible with the system to be migrated during the migration process, wherein the migration assessment agent is a network model that is generated through prior knowledge and can perform migration assessment on the system migration process; the server 105 can, for example, use the migration transformation agent to evaluate the library package corresponding to the target application and incompatible with the system to be migrated The server 105 may, for example, use a migration transformation agent to optimize the source code of the target application according to the source code transplantation modification content; the server 105 may, for example, use a migration transformation agent to modify the configuration of the target application according to the configuration modification content; the server 105 may, for example, use a migration implementation agent to automatically migrate the target application on the source system and the library package corresponding to the target application and compatible with the system to be migrated to the system to be migrated in an incremental manner; the migration implementation agent is a network model generated by prior knowledge that can migrate applications and library packages in the process of system migration.

[0058] It should be understood that Figure 1 The number of terminal devices, networks and servers in the figure is only for illustration. The server 105 may be a physical server or may be composed of multiple servers. According to actual needs, it may have any number of terminal devices, networks and servers.

[0059] Figure 2 is a flowchart of a system migration method according to an exemplary embodiment. The method provided by the embodiment of the present disclosure can be executed by any electronic device with computing processing capabilities. For example, the method can be executed by the above Figure 1 The server or terminal device in the embodiment may be executed, or the server and the terminal device may be executed together. In the following embodiments, the server is used as the execution subject for example, but the present disclosure is not limited to this.

[0060] Reference Figure 2 The system migration method provided by the embodiment of the present disclosure may include the following steps.

[0061] Step S202, through the migration evaluation agent, the compatibility of the target application on the source system with the application and the compilation and running environment on the system to be migrated, the adaptability of the executable file, and the adaptability of the configuration are evaluated to determine the source code transplantation modification content or the configuration modification content of the target application corresponding to the library package or executable file that is incompatible with the system to be migrated during the migration process, wherein the migration evaluation agent is a network model generated by prior knowledge that can perform migration evaluation on the system migration process.

[0062] In some embodiments, the migration assessment agent, migration transformation agent and migration implementation agent provided by the present application can be aggregated into one agent (for example, the functions corresponding to the above-mentioned migration assessment agent, migration transformation agent and migration implementation agent are comprehensively provided by the same agent); the above-mentioned migration assessment agent, migration transformation agent and migration implementation agent can be different agents.

[0063] It is understandable that those skilled in the art may aggregate the functions of the above-mentioned migration assessment agent, migration transformation agent and migration implementation agent into one agent, two agents or three agents for implementation, or may split them into multiple agents for functional implementation, and this application includes the above-mentioned situations.

[0064] In some embodiments, the above-mentioned intelligent agent can be a network model generated by prior knowledge training and capable of performing migration evaluation on the system migration process. For example, it can be a large model (a network model with more parameters) trained by prior knowledge in the field of system migration. Of course, the intelligent agent in this application can also be a small model (a network model with fewer parameters) that has been trained in advance.

[0065] In some embodiments, data on the source system can be migrated to the system to be migrated. The source system can include multiple applications, and the multiple applications can include a target application. Below, this application will take the target application as an example to explain how to migrate data on the source system to the system to be migrated. Those skilled in the art can obtain a technical solution for migrating all data on the source system to the system to be migrated based on the embodiments provided in this application, and this application will not repeat this.

[0066] In some embodiments, the system migration process between the source system and the system to be migrated can be evaluated by a migration evaluation agent.

[0067] For example, the compatibility of the target application on the source system with the application and the compilation and running environment on the system to be migrated (for example, evaluating the compatibility of the dependent libraries or dependent packages of the target application, the compatibility of the running environment of the dependent libraries or dependent packages, etc.) can be evaluated to obtain an evaluation result (such as a library package that is incompatible with the system to be migrated).

[0068] For another example, the adaptability of the executable file of the target application on the source system on the system to be migrated may also be evaluated to obtain an evaluation result (such as the source code migration modification content corresponding to the executable file).

[0069] For another example, it is also possible to evaluate whether the configuration of the target application on the source system is compatible with the system to be migrated, such as whether it is compatible with the software and hardware of the system to be migrated, and obtain evaluation results (such as configuration modification content of the target application).

[0070] Step S204, transforming the library packages corresponding to the target application and incompatible with the system to be migrated through a migration and transformation agent; wherein the migration and transformation agent is a network model generated based on prior knowledge and capable of transforming the library packages and codes during the system migration process.

[0071] In some embodiments, the incompatibilities between the system to be migrated and the source system can be transformed by a migration transformation agent.

[0072] For example, the incompatible library packages between the migration system and the source system can be transformed. For example, the incompatible library packages can be rewritten, rebuilt, or the execution environment of the incompatible library packages can be transformed, etc. This application does not limit the specific transformation content of the library packages.

[0073] Step S206, the migration and transformation agent optimizes the source code of the target application according to the source code transplantation and modification content.

[0074] In some embodiments, the migration and transformation agent can optimize the source code of the target application according to the source code transplantation modification content, so that the transformed source code can adapt to the system to be migrated, for example, adapt to the software and hardware conditions of the system to be migrated.

[0075] Step S208: the migration and transformation agent modifies the configuration of the target application according to the configuration modification content.

[0076] In some embodiments, the migration and transformation agent can modify the configuration of the target application according to the configuration modification content so that the modified content can adapt to the transformed system to be migrated, for example, adapt to the compilation and running environment, executable files, and software and hardware conditions of the system to be migrated.

[0077] Step S210, the target application on the source system and the library package corresponding to the target application and compatible with the system to be migrated are automatically migrated to the system to be migrated in an incremental manner through the migration implementation agent; wherein the migration implementation agent is a network model generated by prior knowledge that can migrate applications and library packages during the system migration process.

[0078] In some embodiments, after the transformation of incompatible items between the source system and the system to be migrated is completed through the migration transformation agent, the data to be migrated on the source system (such as the target application, and the library package corresponding to the target application and compatible with the system to be migrated) can be automatically migrated to the system to be migrated in an incremental manner through the migration implementation agent.

[0079] The technical solution provided by the above embodiment, combined with the method of intelligent agent, can significantly reduce manual intervention and improve the migration efficiency of the operating system with the help of intelligent agent scheduling algorithm. The LLM intelligent agent's pre-migration assessment can scan the operating system status and automatically analyze the migration requirements; the migration transformation intelligent agent performs corresponding transformations on incompatible items and dependent software packages in the migration assessment; during the migration implementation process, the intelligent agent can make the best decision based on the existing knowledge base and real-time data, such as selecting the most suitable migration tool, predicting migration risks, optimizing the configuration of the target system, etc., so as to better implement incremental migration, improve compatibility and dependency issues, and improve the success rate and efficiency of operating system migration.

[0080] Figure 3 The present invention is a flowchart showing a method for evaluating the compatibility between an application and a compilation and execution environment according to an exemplary embodiment.

[0081] refer to Figure 3 The above method for evaluating the compatibility of an application with a compilation and running environment may include the following steps.

[0082] Step S302, using the migration assessment agent to scan at least one of the dependent packages, static libraries and dynamic libraries of the target application in the source system, and to scan the dependent packages, static libraries and dynamic libraries in the system to be migrated.

[0083] Step S304, the migration assessment agent compares at least one of the dependency packages, static libraries, and dynamic libraries of the target application in the system to be migrated with the dependency packages, static libraries, and dynamic libraries in the system to be migrated, and determines the dependency package differences, static library differences, or dynamic library differences between the source system and the system to be migrated.

[0084] The above method can accurately determine whether there are dependency packages, dependency libraries, etc. that meet the target application in the system to be migrated, and accurately give the dependency package differences, static library differences or dynamic library differences between the source system and the system to be migrated.

[0085] Figure 4 The figure is a flow chart of a method for evaluating the adaptability of an executable file according to an exemplary embodiment.

[0086] refer to Figure 4 , the above executable file adaptability evaluation method may include the following steps.

[0087] Step S402: Scan the software and hardware of the system to be migrated by the migration assessment agent to determine the software and hardware information of the system to be migrated.

[0088] Step S404: Decompile the binary executable file of the target application on the source system through the migration assessment agent to obtain the source code of the target application on the source system.

[0089] Step S406, determining the code migration modification content of the source code of the target application according to the hardware information of the system to be migrated and the source code of the target application on the source system, so as to adjust and optimize the software and hardware compatibility of the source code through the code migration modification content.

[0090] Through the above method, the modified source code can be efficiently and automatically adapted to the system to be migrated.

[0091] In some embodiments, the adaptability of the configuration of the target application on the system to be migrated can also be evaluated by the migration assessment agent. For example, the migration assessment agent can provide correction suggestions for the application running configuration file after the target application is migrated based on the incompatible library package or source code migration modification content of the system to be migrated or the hardware and software conditions of the system to be migrated. Through the above method, the modified configuration can be adapted to the compatibility of the modified compilation and operation environment, the executable file, and the hardware and software conditions of the system to be migrated.

[0092] Figure 5 The figure is a flow chart showing a method for modifying a library package according to an exemplary embodiment.

[0093] refer to Figure 5 The above library package transformation method may include the following steps.

[0094] Step S502: If the migration assessment agent determines that the target application uses a closed-source dependency package, static library, or dynamic library in the source system.

[0095] Step S504, the migration and transformation agent replaces the closed-source dependency packages, static libraries or dynamic libraries with open-source dependency packages, static libraries or dynamic libraries.

[0096] In step S506, if there is no open source dependency package, static library or dynamic library, the migration and transformation agent rewrites the open source dependency package, static library or dynamic library based on prior knowledge and the specifications of the system to be migrated.

[0097] The above method can transform compatible library packages efficiently and accurately through the migration and transformation agent.

[0098] Figure 6The figure is a flow chart showing a method for modifying a library package according to an exemplary embodiment.

[0099] refer to Figure 6 The above library package transformation method may include the following steps.

[0100] Step S602: If the migration assessment agent determines that the target application uses a private dependency package, static library, or dynamic library in the source system, then determine the development framework of the private dependency package, static library, or dynamic library.

[0101] Step S604: If the private dependency package, static library or dynamic library is developed through a standard framework, the private dependency package, static library or dynamic library on the source system is directly migrated to the system to be migrated.

[0102] Step S606: If the private dependency package, static library or dynamic library is developed through a non-standard framework, the migration and transformation agent transforms the code according to the development specifications of the standard framework.

[0103] Step S608, if the private dependency package, static library or dynamic library is developed using a compiled language, the code segments of the private dependency package, static library or dynamic library are transformed through the migration and transformation agent to make the private dependency package, static library or dynamic library compatible with the runtime of the system to be migrated.

[0104] The above method can transform compatible library packages efficiently and accurately through the migration and transformation agent.

[0105] In some embodiments, the target application on the source system and the library packages corresponding to the target application and compatible with the system to be migrated can be automatically migrated to the system to be migrated in an incremental manner through the following method: when the migration assessment agent determines that the system to be migrated does not need to be modified when migrating the target application, the migration implementation agent downloads the target software package required for migrating the target application from the system to be migrated according to the software package mapping relationship between the source system and the system to be migrated; the migration implementation agent creates an initial memory file system of the system to be migrated based on the target software package, so as to perform software upgrades and configuration restoration on the target software package in the initial memory file system when the system to be migrated is restarted.

[0106] In some embodiments, the target application on the source system and the library package corresponding to the target application and compatible with the system to be migrated can also be automatically migrated to the system to be migrated in an incremental manner through the following methods, including: if the target application is an application of an interpreted language, the target application is directly deployed to the system to be migrated through the migration implementation agent; if the target application is an application of a compiled language, the migration implementation agent compiles the target application based on the compiler on the system to be migrated, and deploys it to the system to be migrated after compilation.

[0107] The technical solution provided by the embodiment of the present application, combined with the method of the intelligent agent, can significantly reduce manual intervention and improve the migration efficiency of the operating system with the help of the intelligent agent scheduling algorithm. The LLM intelligent agent's pre-migration assessment can scan the operating system status and automatically analyze the migration requirements; the migration transformation intelligent agent performs corresponding transformations on the incompatible items and dependent software packages in the migration assessment; during the migration implementation process, the intelligent agent can make the best decision based on the existing knowledge base and real-time data, such as selecting the most suitable migration tool, predicting migration risks, optimizing the configuration of the target system, etc., so as to better implement incremental migration, improve compatibility and dependency issues, and improve the success rate and efficiency of operating system migration.

[0108] The present application also provides a system migration system and a system migration method.

[0109] Figure 7 A system migration system is shown according to an exemplary embodiment.

[0110] like Figure 7 As shown, the system migration system is mainly divided into user layer, agent layer and operating system layer.

[0111] The user layer has a user interaction interface where users can propose migration requirements, view the generated migration plan, and see the progress and problems during the migration process.

[0112] Agent layer: It is divided into agent management module and agent module. The agent management module can schedule, coordinate and allocate resources to each agent according to the task.

[0113] The agent module contains the following three agents:

[0114] Migration assessment agent: Before the migration is implemented, the migration assessment agent accesses the operating system through the SDK interface, calls the tool to scan the system to be migrated, collects basic information about the kernel, software package, and system configuration, and compares and analyzes it with the target system. It provides impact analysis and solutions for incompatible items and dependent software packages, and mainly includes three assessments: compatibility assessment between the application and the compilation and running environment, adaptation and transformation assessment of executable files, and adaptation and transformation assessment of configurations.

[0115] Migration and transformation agent: Based on the evaluation results of the migration and evaluation agent, the migration and transformation agent calls the knowledge base and other capabilities through the SDK interface to transform the software packages, runtime libraries, and compilers in the operating system application accordingly;

[0116] Migration implementation agent: The migration implementation agent migrates the operating system according to the evaluation results of the migration evaluation agent, and implements incremental migration in steps for the operating system components that do not need to be modified; for the operating systems that need to be modified, after the modification agent completes the modification of the library package and compiler, it migrates them to the source system.

[0117] Operating system layer: It is further divided into software layer, kernel layer and hardware layer.

[0118] Software layer: includes software applications and related runtime libraries;

[0119] Kernel layer: includes scheduler, file system, driver and related system call interface.

[0120] Hardware layer: includes CPU, GPU, storage devices and other hardware.

[0121] The following is a detailed description of the workflow of each module in the agent layer:

[0122] Agent management module: According to the task volume of operating system migration and the existing resource utilization, the different processes involved in operating system migration are divided. For example, n operating system migrations are divided into evaluation task n, transformation task n and migration task n. Priorities are assigned to these tasks based on dependencies, and tasks are assigned to different agents in turn according to priority, and corresponding resources are allocated to the agents.

[0123] Migration assessment agent: mainly includes the following three assessments: compatibility assessment between application and compilation and running environment, adaptation and transformation assessment of executable files, and adaptation and transformation assessment of configurations.

[0124] Compatibility assessment between applications and compiled runtime environments: assess the compatibility between applications and the compiled runtime environments on the systems to be migrated. Based on the characteristics of the application type, the assessment agent calls relevant tools through the SDK interface to scan dependent packages, static libraries, and dynamic libraries in the operating system, including basic rpm (a software package management tool) and yum source (a tool for installing and managing software packages) scanning, dynamic so library (shared object library or dynamic link library) file or dll file (an executable file) scanning, dependent source code scanning, etc. Based on the scanning results, the assessment and transformation agent compares the operating system to be migrated with the source system, gives the differences between the dependent packages (such as rpm) of the environment to be migrated and the target dependent packages, the differences between the dynamic libraries and the target dynamic libraries, etc., and returns the results to the user interaction interface;

[0125] Adaptation and transformation evaluation of executable files: For binary executable files of applications or business systems, the evaluation agent analyzes the porting and modification content of the code through decompilation (converting the compiled binary code into high-level language code) and other means. At the same time, based on the characteristics of the executable files, it proposes a list of recommendations for the adaptation environment and feeds back to the migration implementation agent.

[0126] During the code transplantation process, the source code needs to be modified to adapt to the hardware and software environment of the target system. These modifications may involve multiple aspects: 1. Hardware compatibility adjustment (for different hardware platforms' CPU, memory or peripherals, etc.) to optimize the code and modify the parts that directly interact with the hardware, such as interrupt processing, I / O operations, etc.; 2. Operating system interface adaptation

[0127] Configuration adaptation and transformation evaluation: Aiming at the differences in environment and code transformation before and after application migration, the evaluation agent can give correction suggestions for application running configuration files in different environments, such as port connection correction, dependent library call configuration correction, etc.

[0128] Migrate and transform the agent: This mainly includes the following two transformations: transformation for the runtime and transformation for the compiler:

[0129] Runtime library-oriented transformation: The first step of application transformation is to adapt to the standard dependencies of the operating system. The migration and transformation agent replaces the original dependency packages, dynamic libraries, and static library files of the application with versions compatible with the system to be migrated. If the agent detects that the application uses privately developed or closed-source dynamic dependencies, the transformation is difficult. The migration and transformation agent replaces it with an open source version. If the open source version is not obtained, it is rewritten based on the specifications of the operating system according to prior knowledge;

[0130] Compiler-oriented transformation: The second step of application transformation is to transform the privately developed part to adapt it to the standard runtime or standard compilation environment of the domestic operating system. The evaluation agent has completed the evaluation in the previous step. For high-level language applications developed using the standard framework, smooth migration can be achieved without transformation, and the next step of migration implementation can be directly entered; for private classes outside the standard framework, the migration and transformation agent will transform the relevant code according to the compilation specifications; for applications involving compiled languages, when the privately developed class library is not compatible with the operating system runtime, the migration and transformation agent will transform the corresponding code segment.

[0131] Migration implementation agent: The migration implementation agent automatically migrates the applications to be migrated and the supporting library packages to the source system in an incremental manner.

[0132] When the migration assessment agent evaluates that no modification is needed, the migration implementation agent first downloads the required software packages from the operating system to be migrated in advance according to the software package list installed in the current system and the software package mapping relationship between the original operating system and the operating system to be migrated, and creates upgrade-initramfs (a system file) based on the software packages of the operating system to be migrated. After the next restart, the system automatically enters upgrade-initramfs and triggers the in-place upgrade of all software packages. After all software packages are upgraded in-place, it automatically restarts to enter the system configuration restoration phase. After all information is configured, the system restarts to enter the new operating system;

[0133] The migration evaluation agent provides feedback to the agent management module for applications identified as interpreted languages, which then sends the task to the migration implementation agent, which is then deployed to the new operating system through the migration implementation agent. For applications in compiled languages, the agent management module sends the task to the migration transformation agent after receiving feedback from the evaluation agent. The migration transformation agent is based on the trusted version of the compiler, and after compilation is completed, it is deployed to the new operating system by the migration implementation agent.

[0134] In response to missing and different library packages, the migration assessment agent evaluates whether the existing library packages can replace the corresponding dependencies of the source system. If so, it will be transferred to the migration implementation agent for updating and upgrading. If not, it will be migrated to the source system after the migration transformation agent completes the transformation. In response to differences in business systems, if the configuration can be modified or the code can be corrected, the migration implementation agent will call the relevant self-migration tool to make corrections, and then deploy it to the corresponding operating system for subsequent data migration.

[0135] The above system migration method can be Figure 8 The flowchart shown is described.

[0136] refer to Figure 8 , the above system migration method may include the following steps:

[0137] Step 801: The user provides information and requirements of the system to be migrated and the source system.

[0138] Step 802: The agent management module decomposes the task and assigns it to each agent.

[0139] Step 803: The migration assessment agent scans the operating system information and performs an assessment.

[0140] Step 804, determine whether modification is needed.

[0141] If modification is required, execute step S805.

[0142] If no modification is required, execute step S806.

[0143] Step 805, migrate and transform the intelligent body to transform the runtime library and compiler.

[0144] Step 806, migration implementation agent upgrades software package, deploys applications, and implements incremental migration.

[0145] Step 807, end.

[0146] The difference between this embodiment and the related art is that:

[0147] 1. The related technologies mainly rely on vendor tools supplemented by manual operations to migrate the operating system, while this patent introduces an intelligent agent that can realize automatic migration without manual intervention. It can not only make the best decision for operating system migration based on the existing knowledge base and real-time data, but also perform intelligent management, and perform related scheduling and resource allocation for the evaluation, transformation and migration intelligent agents;

[0148] 2. The related technology can only migrate the operating system one by one, but the patented method can realize batch operating system migration under the effective scheduling of the intelligent agent management module, greatly improving the efficiency of migration;

[0149] 3. The relevant technology only focuses on migrating the operating system itself, but ignores the adaptation of the operating system application. The transformation method proposed in this application (corresponding to the migration and transformation intelligent agent) can effectively improve the availability of the application after migration and avoid the situation where the application is unavailable after migration.

[0150] The above embodiments have the following beneficial effects.

[0151] 1. Introduce intelligent agents into the operating system migration process, including migration evaluation agent, migration transformation agent and migration implementation agent. The migration evaluation agent has three evaluation modules: compatibility evaluation between application and compilation environment, adaptation and transformation evaluation of executable files, and adaptation and transformation evaluation of configurations; the migration and transformation agent has two transformation modules: transformation for runtime library and transformation for compiler.

[0152] 2. Compared with traditional methods, it focuses more on application adaptation and migration, and proposes runtime library-oriented and compiler-oriented modifications specifically for application software adaptation to improve the availability of applications in new operating systems.

[0153] 3. Agent management can schedule and allocate resources for each agent. By scheduling the agents, the synchronous migration of multiple operating systems can be achieved, effectively improving the migration efficiency.

[0154] It should be particularly pointed out that each step in each embodiment of the above system migration method can be mutually crossed, replaced, added, or deleted. Therefore, these reasonable permutations, combinations, and transformations of the system migration method should also fall within the protection scope of the present disclosure, and the protection scope of the present disclosure should not be limited to the embodiments.
