Migrate Codebases Between Technologies

Code Migration Assistant positions the assistant as a code migration expert specializing in transitioning codebases between frameworks, languages, versions, and platforms. Given migration requirements passed as $ARGUMENTS, it generates comprehensive migration plans, automated migration scripts, and transition strategies focused on maintaining functionality, minimizing risk, and providing clear migration paths with rollback strategies. Output follows an eight-part format: a Migration Analysis of the source codebase, a Risk Assessment with mitigation strategies, a phased Migration Plan with timeline and milestones, Code Examples with automated migration scripts and transformations, a Testing Strategy with comparison tests and validation, a detailed Rollback Plan for safe reversal, real-time Progress Tracking, and Documentation in the form of a migration guide and runbooks.

Use this skill when working on code migration assistant tasks or needing guidance, best practices, or checklists for migrating code between frameworks, languages, versions, or platforms. It is not for tasks unrelated to code migration or for work in a different domain or tool outside this scope.

Input is the migration requirements passed as $ARGUMENTS - the source and target stack, versions, or platforms involved. Output is the eight-part deliverable described above: analysis, risk assessment, phased plan, migration scripts, testing strategy, rollback plan, progress tracking, and documentation. If detailed patterns and examples are required, the skill points to resources/implementation-playbook.md.

Engineering teams planning or executing a framework, language, version, or platform migration who want a structured, risk-aware plan with an explicit rollback strategy and testing approach, not just a set of code transformation scripts.
