Refactoring models from one django app into two

I've got an app which has grown too big and I'd like to split it into two. It's not an easy task code-wise, but I'm more afraid of the database migrations I'll have to perform. Is there a proven way of doing such kind of thing?

Currently my thoughts are something like this:

• Use south
• Copy models to another app
• Make a data migration to copy relevant models from one app to the other
• Make another migration that removes the now unused models from the old 开发者_运维百科app
• Will have to make a script that does those operations in correct order

Has anybody done anything like this?

No need to do any database migrations if you don't want to. Just set the db_table Meta attribute on your models to refer to the old names, and everything will be perfectly happy.
