How to Safely Rename a Django App Without Breaking Migrations or Data

Renaming a Django application is more complex than it appears, especially when the app already has migrations and production data. Django uses the app name across migration history, content types, permissions, and database table names, making careless changes risky. The safest approach is to rename only the Python package directory while keeping the original app label in apps.py, which preserves Django's internal recognition of the application. This method avoids the need to manually alter the django_migrations or django_content_type tables. Going further to also change the Django app label itself requires careful handling of database tables, foreign keys, migration files, and third-party package references to avoid data inconsistencies.
