Drizzle Migration

Safe database schema changes following Drizzle ORM best practices.

Golden Rules

1. NEVER edit existing migration files
2. ALWAYS update schema first, then generate
3. ALWAYS review generated SQL before applying
4. ALWAYS test in development before staging/production

Workflow

1. Plan the Change

• Identify tables and columns affected
• Consider data migration needs
• Plan for backwards compatibility
• Document rollback strategy
