Recommended next stepStart with BDBMIG-101
Open the first ticket for its prerequisites, acceptance criteria, verification plan, and an editable task draft.
What the engineer takes away
Practice migration tooling, lock reasoning, and clear developer feedback.
What the team gains
Provide reviewers with repeatable migration checks and explicit recovery limits.
Before you start
- Create a disposable local database with synthetic subscriptions and a separate scratch database; author all fixtures locally.
Delivery agreement
Deliver a local review CLI and SQL rehearsals; do not connect to production databases.
AI tools are welcome during implementation. Record assumptions, review the result, and verify its behavior.
Delivery phases
- PHASE 1
Make proposed SQL and risk assumptions visible.
- PHASE 2
Check application compatibility and interrupted execution.
- PHASE 3
Package evidence and recovery steps for review.
