Plan Safer Deprecations and Migrations

Legacy systems create maintenance cost and migration risk. This skill provides staged plans, compatibility checks, and rollback guidance for controlled change.

測試它

正在使用「deprecation-and-migration」。 We need to rename a heavily used database column without downtime.

預期結果:

Add the new nullable column, deploy dual writes, backfill in throttled batches, switch reads after validation, stop writing the old column, then drop it in a later deployment.

正在使用「deprecation-and-migration」。 A legacy API has active consumers but a replacement is ready.

預期結果:

Inventory consumers and undocumented behavior.
Publish the replacement and migration guide.
Migrate consumers incrementally behind a feature flag.
Verify usage reaches zero before removing the legacy API.

All 28 external-command findings are false positives caused by Markdown backticks, fenced code examples, and documented command names; the skill does not execute them. The three reconnaissance findings are ordinary migration rationale and verification checklist text, with no evidence of prompt injection, data exfiltration, or malicious intent.

你可以打造什麼

Retire a legacy service

Assess consumers, select a replacement, and create an incremental plan for migration, verification, and removal.

Migrate an API safely

Design compatibility layers, feature-flag cutovers, documentation, and consumer-by-consumer migration work.

Change a production schema

Plan additive schema changes, batched backfills, dual writes, read cutovers, and a later destructive cleanup.

試試這些提示

Assess a deprecation

Should we deprecate this system? Review its value, consumers, replacement options, migration cost, and ongoing maintenance cost. Return a decision with evidence needed.

Create a migration plan

Create a staged migration plan from [old system] to [replacement]. Include consumer discovery, documentation, verification, rollout gates, rollback actions, and removal criteria.

Choose a migration pattern

Compare the Strangler, adapter, and feature-flag patterns for migrating [system]. Recommend one based on traffic control, compatibility, ownership, and rollback needs.

Design an expand-contract change

Design a production-safe expand, migrate, and contract plan for changing [schema element]. Include dual writes, batched backfill, validation, read cutover, rollback, and cleanup gates.

最佳實務

Measure active consumers and dependencies before setting a removal date.
Keep each migration phase independently deployable, observable, and reversible.
Ship destructive schema changes only after compatibility and zero-usage checks pass.

避免

Deprecating a system before a working replacement and migration guide exist.
Renaming or dropping a production column in the same deployment as the code cutover.
Running a large unthrottled backfill or relying on an untested rollback.

常見問題

What does this skill help plan?

It helps plan deprecations, service migrations, API transitions, feature cutovers, and production database schema changes.

Does it execute migration commands?

No. It produces plans and guidance. You must review and run commands through your own tested operational process.

What is expand-contract migration?

It adds a compatible schema shape, migrates data and reads gradually, then removes the old shape in a later deployment.

When should a deprecation be compulsory?

Use a hard deadline when security risk, blocking limitations, or unsustainable maintenance cost justifies mandatory migration.

How should I reduce migration risk?

Measure usage, migrate incrementally, use observability and feature flags, test rollback paths, and separate destructive changes.

Can it choose the right migration pattern?

It can compare common patterns against your constraints, but your team must validate the recommendation against architecture and operations.
