File System Migration Planning Across Different Architectures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional file system migration approaches require significant downtime and labor-intensive manual processes to preserve namespace and policies when transitioning to a new architecture, especially when source and destination file systems have different architectures.
Innovation Solution
A system and method for creating a migration plan that incorporates operator input to optimize the structure, organization, and policy implementation of a destination file system, allowing for automated migration while accounting for different architectures, using a planner to generate a migration plan that maps and replicates file system objects and policies based on operator preferences and destination-specific characteristics.

Engineering Contradiction Analysis
1Adaptability or versatility
If conventional file system migration approaches are used, then the source file system can be migrated to a new architecture, but significant downtime is required and manual labor is intensive
Solution Approach 1:
The system performs preliminary actions by creating a migration plan before actual migration occurs. The plan includes pre-mapping source file system objects to destination objects, pre-configuring policy mappings, and pre-allocating destination resources. This advance preparation enables the actual migration to execute quickly with minimal downtime, as the complex decision-making and configuration work is completed beforehand.
Solution Approach 2:
The migration plan acts as an intermediary between the source file system and destination file system. It contains mapping relationships and policy translations that mediate the migration process, allowing objects to be transferred between different architectures without requiring manual intervention during the actual migration execution.
2Adaptability or versatility
If conventional file system migration approaches are used, then the source file system can be migrated to a new architecture, but manual labor is intensive to preserve namespace and policies
Solution Approach 1:
The system implements self-service by automatically generating the migration plan through operator input and system analysis. The planner component autonomously maps source file system objects to destination objects, automatically translates policies between different architecture formats, and configures resource allocations without requiring manual administrative intervention for each individual mapping or policy translation.
Solution Approach 2:
The system handles parameter changes by automatically adapting policy parameters when translating between different file system architectures. The migration plan includes parameter mappings that transform source architecture policies into destination architecture policies, adjusting parameters like export policies, security settings, and resource allocations to match the destination system's requirements without manual reconfiguration.
3Ease of operation
If automated migration is implemented, then manual labor is reduced, but the migration plan must account for different architectures and optimize destination structure
Solution Approach 1:
The migration plan is segmented into distinct components: object mappings, policy mappings, and resource allocations. Each segment handles a specific aspect of the migration, allowing the complex overall process to be managed through separate, specialized sub-plans. This segmentation enables automated generation while maintaining clarity and manageability of the overall migration strategy.
Data Source
AI summary
A migration plan is created that is based at least in part on an operator input. The resources of a destination file system are provisioned based on the migration plan. One or more processes to migrate the source file system for the provisioned resources of the destination file system are then configured based on the migration plan.
