Framework Migration Code Migrate

This is a structured prompt for handling code migrations between frameworks, languages, or versions. It walks you through eight phases from initial analysis to rollback planning, which is honestly the right scope since migrations fail most often from poor planning rather than bad code transforms. You get risk assessment, phased timelines, automated script generation, and comparison testing strategies. The format is pretty rigid with its numbered output sections, but that's probably a feature here since ad hoc migrations are how you end up with half-migrated codebases in production. Best for substantial migrations where you need documentation and rollback procedures, less useful for quick version bumps.
