Upgrade netbox from version 3.3.10 to 3.4.0

[pmarchal25]

Hi everyone,

I had netbox version 2.8.6 installed in a virtual machine and i wanted to upgrade to the new version (3.6.0) without losing my databases information. I have been following the steps and everything was okey until i tried to upgrade netbox version 3.3.10 to 3.4.0. When i ran the upgrade.sh script this error appeared:

django.db.utils.DataError: Unable to proceed with deleting asn field from Provider model: Found 1 providers with legacy ASN data. Please ensure all legacy provider ASN data has been migrated to ASN objects before proceeding. Or, set the NETBOX_DELETE_LEGACY_DATA environment variable to bypass this safeguard and delete all legacy provider ASN data.

and i don't know how can i solve the problem. Thank you so much.

Best regards.

The error tells you how to solve the problem. Your choices are:

1. "ensure all legacy provider ASN data has been migrated to ASN objects before proceeding". That is: create the new ASN objects, and then empty out the ASN fields in the Provider objects, before upgrading. The ASN model was introduced in Netbox v3.1, but since you said you've already upgraded to 3.3.x, that should be fine.
2. "set the NETBOX_DELETE_LEGACY_DATA environment variable" - then when you run upgrade.sh, it will silently delete the ASN fields in the Provider objects regardless of whether there was any data in them.

Note: if you're upgrading to Netbox v3.4, you should choose the latest in that branch (which is v3.4.10) rather than v3.4.0. All the later versions have bug fixes applied.

Do not attempt to upgrade to the v3.6.0 beta except in a virtual machine that you're happy to throw away. There is no supported upgrade path from v3.6.0 beta to the v3.6.0 final release when it appears (or any other release, for that matter)

Hi, the migration has been done but the web server does not start (i have reset the virtual machine and the netbox service). I think that the problem could be about the database Maybe but i am not sure.

Start by looking at what the webserver logs say: journalctl -eu netbox

i have checked it before but the file is empty. I have the netbox reboot by crontab (@reboot /opt/netbox/start.sh >> /tmp/crontab.log 2>&1) and maybe the problem is that (but i have been checking the paths and everything is okey. When i see the crontab logs this appear:

Hi,

i have just solved the problem. I had to install some dependencies on the root directory of netbox and clean the pycache and the webserver right now is working. Thank you so much for your help, i hope you have a nice weekend!

Best Regards.
