What migration does

Implement reversible compatibility-safe transitions. Use for schema, data, API, protocol, configuration, or dependency migrations requiring rollback and preservation proof.

Migration

Map current readers, writers, data shape, compatibility window, and ownership before editing.

  • Define forward path and rollback path.
  • Preserve existing data; make destructive steps explicit and separately authorized.
  • Keep mixed-version operation safe where rollout can overlap.
  • Sequence expand, migrate, verify, then contract when applicable.
  • Make retries idempotent and partial failure observable.
  • Verify old and new paths at required transition stages.

Stop after requested stage passes; do not perform later destructive contraction implicitly.

Use when building any feature that accepts untrusted data, manages user sessions, or interacts with third-party services. Use when auditing dependencies for known vulnerabilities, triaging package-manager audit findings, or assessing supply-chain risk in a new package.
