| Step 2 | Syntax error in migration | Fix SQL; re-run |
| Step 4 | Data migration fails mid-run | Script should be idempotent; fix and re-run; if partial data, document manual cleanup |
| Step 5 | Test migration fails | Run DOWN migration to revert; fix UP migration; retest |
| Step 5 | Rollback test fails | Fix DOWN migration; ensure DOWN fully reverts UP before retrying |
Never apply migrations to production without testing UP and DOWN in a non-prod environment first.
Migration created, tested, and code updated. Ready for review.
