I forgot to mention that I found one error in the last upgrade procedure in the migrate part. It is about the urls.py file. It's about the import from django.conf.urls the "url", that now is inexistent. After searching  around, I've edited urls.py like below. That saved me from modifying more things in that file.

### from django.conf import settings ### mod. 30/10/22 ###from django.conf.urls import include, url from django.conf.urls import include from django.urls import re_path as url #####
