Migrations are high-risk changes that alter shared systems; this skill provides a structured approach to plan deployments with clear rollback strategies, testing, and observability to prevent outages.
Draft a complete migration plan for the upcoming production change, including rollback steps and monitoring.

A safe database schema migration requires a structured plan analyzing blast radius, applying the Expand-Contract pattern to keep systems in sync, and defining explicit rollback scripts and success criteria to prevent outages.
To execute a canary rollout, you implement progressive delivery strategies that use staged rollouts and automated rollback triggers, monitoring system state and blast radius to safely deploy service updates.
The Expand-Contract pattern works by expanding the new system alongside the old, synchronizing data during the transition, and contracting the old system only after validation, preventing downtime during infrastructure updates.
Yes, you can configure automated rollback triggers as part of your progressive delivery strategy, allowing staged rollouts to automatically revert if monitoring detects failures during the production migration.
You need a documented migration plan with attestation workflows when executing high-risk changes to shared systems, ensuring you capture system state before, during, and after migrations to prevent outages.
Pre-migration checks should include analyzing the current system state and blast radius, defining success criteria, and preparing rollback scripts to ensure the production rollout maintains observability and safety.
