What scripts do well
Encode local conventions fast, especially for one repository with known quirks.
Comparison
CPMigrate vs ad hoc migration scripts
Repo-specific scripts often start as the quickest way to migrate one solution. They usually become expensive when teams need docs, repeatability, safe updates, and CI-friendly output across more than one repository shape.
Where scripts drift
Logic gets copied, edge cases multiply, and rollback or analysis behavior rarely stays consistent.
Where CPMigrate fits
A maintained CLI for migration, dependency analysis, auto-fix, package updates, JSON output, and backup-aware workflows.
