backend-migrations
Create and manage database migrations for schema changes, ensuring zero-downtime deployments and data integrity. Use this skill when creating migration files, modifying database schemas, adding or altering tables/columns/indexes, or working with migration tools like Alembic, Flyway, Liquibase, or framework-specific migration systems (Django migrations, Rails migrations, Prisma migrations). Apply this skill when implementing reversible migrations with up/down methods, handling data migrations separately from schema changes, creating indexes on large tables, or planning backwards-compatible schema changes for high-availability systems. This skill ensures migrations are version-controlled, focused, safe to rollback, and compatible with CI/CD pipelines and zero-downtime deployment strategies.
