NetBox version

Steps to Reproduce

Running upgrade.sh script fails with

ERROR: Database schema migrations are out of synchronization. (No
data has been lost.) If attempting to upgrade to NetBox v3.0 or
later, first upgrade to a v2.11 release to ensure schema migrations
have been correctly prepared. For further detail on the exact error,
run the following commands:

source /opt/netbox-system/venv/bin/activate
python3.7 netbox/manage.py showmigrations

When i run show migrations

I have deleted all secrets and secret roles as well.

Expected Behavior

Migrations to be applied and upgrade to finish

Observed Behavior

Upgrade fails

This error references a migration file that does not exist in the v3.0 code base, which suggests an error with your installation. It's likely that you've copied the v3.0 code into the v2.11 installation, rather than replacing it. I recommend starting over with your original v2.11.12 installation and trying the entire upgrade procedure again.
