This is the exact error I received

Applying database migrations (python3 netbox/manage.py migrate)...

The above exception was the direct cause of the following exception:

In a few other issues, I need to upgrade to 3.7.8. I will follow that procedure and perform the update.

It would be beneficial if there were some easy-to-find migration steps and procedures to follow. Just a quick workflow showing which versions must be upgraded to which version from which versions.
