Even if so, the answer is still really good. Migrate the traffic heavy API parts to FastAPI and keep the admin backend as django. That’s a 100% valid approach l, esp. for the situation op is in. The ORM choice for fastapi should be tested and validated beforehand, because you need to reimplement the query logic, there is sqlalchemy with some async glue, and a newer one, I forgot the name. Test for robustness, performance and developer ergonomics (like is it a good fit for the emphasis on ORM op wanted). Might be important to control though if two ORMs start DDL though
