Comment (by David Freiholtz):
With reservation for that I'm still pretty much a beginner and that I only
tried it on a small project.
I had great help to migrate from a built-in User model to a custom User
model from this page:
https://code.djangoproject.com/ticket/25313
And this one https://simpleisbetterthancomplex.com/article/2021/07/08
/what-you-should-know-about-the-django-user-model.html
Then I wrote up a short bullet list on how to do it on my django based
mastodon

TL;DR
First, only use get_user_model in your code
1. Create a datadump python manage.py dumpdata > datadump.json
2. Create the new user model and set db_table = 'auth_user' in Meta
section.
3. Truncate the database
4. python manage.py makemigrations
5. python manage.py migrate
6. Edit {"model": "auth.user" to {"model": "myapp.customuser" in
datadump.json
7. python manage.py loaddata datadump.json
