Mongodb Migration Expert

This one walks you through MongoDB schema changes the safe way: additive first, destructive later. It enforces a workflow where you add new fields, deploy code that handles both old and new schemas, backfill in batches, then clean up legacy fields in a later release. The indexing guidance is practical, compound indexes match query patterns, and it pushes you to validate with explain before committing. If you're working with multi-tenant collections, it reminds you to lead compound indexes with tenantId. The checklists keep migrations idempotent and observable, which matters when you're touching production data. Solid for teams that need discipline around forward-only migrations.
