How does this skill handle zero-downtime deployments?

It provides multi-phase migration patterns, such as adding columns in a backward-compatible way and backfilling data, to ensure the application remains functional during schema updates.

Can I use this for cross-database migrations?

Yes, the skill includes specific strategies for handling dialect differences, such as transitioning between PostgreSQL-specific features and MySQL-compatible types.

Which ORMs are supported by this skill?

This skill provides specific syntax, best practices, and implementation patterns for major Node.js ORMs including Sequelize, TypeORM, and Prisma.

Does it include safety features for production migrations?

Absolutely. The skill emphasizes transaction-based migrations, idempotent scripts, and checkpoint-based rollback procedures to prevent data loss or service outages.
