Migration from Flask/Django requires learning curve and replacement of familiar tools
6/10 MediumMigrating from Flask or Django to FastAPI requires replacing familiar tools: `requests` must be replaced with `httpx` for async operations, Django REST Framework serializers must become Pydantic models, and the async paradigm shift is non-trivial. FastAPI lacks the built-in ORM and admin panel developers relied on.

Replace `requests` with `httpx` for async HTTP calls. Moving from Django requires more work. You'll switch from Django REST Framework serializers to Pydantic models. FastAPI is lighter weight – no built-in ORM or admin panel.
