-- =====================================================
-- NOTES
-- =====================================================
-- If all tests show PASS:
--   - Migration successful
--   - Safe to update application code
--   - Monitor for 30 days before dropping old tables
--
-- If any tests show FAIL:
--   - Review specific failures
--   - Consider running ROLLBACK script
--   - Fix issues and re-run migration
