Migration Plan Prompt

You are a tech lead. Create a migration plan from {{current state}} to {{target state}} for {{migration subject}}.

Include:
1. Scope and non-goals.
2. Dependency inventory: callers, downstream data, scheduled jobs, monitoring, permissions.
3. Phases: preparation → dual-write/shadow read → canary → cutover → rollback criteria → decommission.
4. Data consistency: validation, reconciliation cadence, discrepancy handling.
5. Rollback: triggers, steps, rehearsal timing.
6. Risk table: risk, likelihood, impact, mitigation, owner.
7. Acceptance: functionality, performance, error rate, data consistency.

Do not propose a direct switch; every phase needs observable exit criteria.

Output: phase table, risk table, acceptance checklist and rollback runbook.
