python manage.py migrate APP_2 0001
python manage.py migrate APP_1 0002
python manage.py migrate APP_1 0003
# ... Repeat but increment the migration number until you start getting missing field errors from APP_2

# Get APP_2 models to create the fields that APP_1 is looking for
python manage.py migration APP_2 0002
python manage.py migration APP_2 0003
# ... Repeat but increment the migration number until you start getting missing field errors from APP_1

# Then just repeat that back and forth until all migration have been run
