Extensible Upgrade Service Automating Application Migration

The system enables self-service automation where the modification orchestration service automatically performs dependency analysis, modifier selection, and application modification without requiring manual intervention. The service autonomously processes migration tasks by executing determined modifiers on target applications, thereby resolving the contradiction between migration capability and time consumption.

The patent replaces manual mechanical processes (manual dependency determination, manual component modification) with an automated computational system. The modification orchestration service uses algorithmic processing to analyze dependencies, select appropriate modifiers, and execute modifications, substituting human labor with automated mechanical-computational systems to improve productivity and reduce time loss.

The system implements universality through reusable modifiers that can be applied across multiple microservices and applications. A single modifier can be determined once and then repeatedly applied to various target applications, enabling the same modification operation to serve multiple purposes and contexts, thereby improving adaptability while reducing redundant development effort.

The system performs preliminary action by determining and preparing modifiers in advance before they are needed for actual application modification. The modification orchestration service pre-processes modification requirements, selects appropriate modifiers, and prepares them for execution, so that when multiple applications need similar changes, the work has already been done once and can be reused, significantly improving productivity.
