[Django]-Is it safe to rename Django migrations file?

✅

This works, with a minor caveat: Django will no longer know that the renamed migration is applied.

So the steps to renaming a migration are:

  1. Rename the file.
  2. Repoint any dependencies to the new file.
  3. If the renamed migration was already applied, apply it again using --fake.

If it’s a brand new migration, 2 and 3 won’t apply, and it’s perfectly fine to rename them.

This is happens in Django every time migrations are squashed. A new file is generated thats contains the class variable replaces, this lists the migration files that are being replaced.

So to rename a file migration file add in the following variable in the Migration class:

replaces = [('app name', 'migration file name'), ]

And everything works like it did before the file change.
