I recently upgraded [0] one of my project [1] to Django v4, from Django v1. The changes from Django 3 to 4 were fairly simple, just one line change in my case. The change log is extremely detailed, it was easy to upgrade. Also, I found a tool called django-upgrade [2] which makes some changes automatically, rest I made manually.
