migrate from django migrations to fastapi alembic

Question

I had a Django service which had an app called "User". This app has 2 tables in, which are being migrated to the database using Django migration system. In order to change the architecture from monolith to micro-service, I broke down User app and add the models and APIs in another Fastapi project. But I didn't separate the database and during this time, I was changing User tables in database using my previous Django project migration system. But now I want to break down tables in the database and move them to the new database. What is the best practices of doing this? And how can I change migrations from Django to alembic?
