# Migration

Migration implements reversible compatibility-safe transitions for schema, data, API, protocol, configuration, or dependency changes. Use it when rollback and preservation proof are required.

**Install:**

```bash
npx degit https://github.com/JuliusBrussee/caveman/tree/main/skills/migration ~/.claude/skills/migration
```

## README

# 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.
