What problem does it solve?

This Skill helps plan, coordinate, and execute database migrations (schema and data) with safe rollouts and explicit rollback strategies, avoiding unintended changes to app logic.

Core Features & Use Cases

• Backward-compatible migration strategy (expand → migrate → contract) to minimize downtime.
• Idempotent, resumable data backfills with progress tracking and rollback readiness.
• App-change coordination to ensure old and new schemas work together during rollout and verification.
• Verification steps and runbooks to prepare production readiness.

Quick Start

Plan the migration, run it in staging, verify results, and prepare rollback documentation.
