Upgrading from 3.4.9 to 3.5.0 problem

[Ordauq]

Hello,

After running upgrade.sh script, I'm getting error when migrations performing -

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

Could anyone please help with troubleshooting this?

Hi, I will suggest saving any custom scrips files in a safe location and removing them from /opt/netbox/netbox/scripts/
Make sure you leave the __init__.py and try sudo ./upgrade.sh again

Thanks,
That was invalid symlink to netbox_v32_migration.py script, after deleting it upgrade process finished successfully.
