✓ 应当这么做

  • ✓ Split every breaking change into expand, migrate and contract phases
  • ✓ Make the migration idempotent so a re-run is a no-op
  • ✓ Rehearse on a production-shaped copy and record the rollback path

✕ 常见反模式

  • ✕ Irreversible destructive steps in the same release as code removal
  • ✕ Big-bang cutovers with no parallel running period
  • ✕ Migrations that depend on manual console steps

◎ 交付前验证

  • ◎ Suite passes in random order and with concurrency enabled
  • ◎ Coverage on the changed module did not drop
  • ◎ Flaky tests reported rather than retried silently
