Database Migration Workflow

Migration request: $ARGUMENTS

Step 1 — Task Card validation (task-coach)

Invoke task-coach with the request above.

The Task Card must classify the task as high risk and include:

  • tables, collections, models, or migration files in scope
  • data backfill or data cleanup requirements
  • deployment ordering and compatibility window
  • rollback or forward-fix strategy
  • lock risk, data risk, and verification commands

STOP here. Show the Task Card and wait for human confirmation.


Step 2 — Migration Plan (architect)

Invoke architect with the approved Task Card.

architect must define the schema/data plan, operational sequencing, compatibility strategy, rollback/forward-fix notes, and test approach.

STOP here. Show the Technical Plan and wait for explicit human approval.


Step 3 — Implementation (implementer)

Invoke implementer with the approved plan.

implementer must keep model and migration changes together, avoid unrelated refactors, and preserve the deployment order specified by architect.


Step 4 — Migration tests (tester)

Invoke tester.

tester must cover migration-sensitive behavior where the stack supports it, including happy path, existing-data edge cases, and rollback/forward-fix notes when automated rollback tests are not practical.


Step 5 — Review (reviewer)

Invoke reviewer.

reviewer must block on missing migration tests, missing data-risk notes, undocumented deployment sequencing, or model/migration drift.


Completion

Report migration files changed, model files changed, tests run, lock risk, data risk, operational sequencing, rollback/forward-fix notes, and residual risk.
