FYI, the following appeared during the first migrate. After running it again the django-admin-index fixture was loaded in properly:

Error: Unable to load django-admin-index fixture (ContentTypeProxy matching query does not exist.: (admin_index.appgroup:pk=544) field_value was '['django_celery_beat', 'periodictask']')

Nearly there, a few final remarks. And we need to update deployment + helm charts, but thats for a separate PR

Can be merged after CI is green
