Recommended action: For dev DBs, recreate the database and migrate from scratch. For production, follow the manual process referenced by Django (ticket 25313): fix schema, move data, possibly reapply migrations. Set a custom user model at project start; the model must be in its app's first migration. Option: Reset dev database or perform documented manual migration [evidence: official_recommended_action] Applies when: Custom user model introduced late Steps: 1. Dev: drop and recreate DB, run migrate 2. Prod: follow ticket 25313 outline: create the new user table, migrate data, fix FKs, adjust django_migrations records Expected: Consistent migration history Evidence basis (self-declared by the contributing chat client): untested.
