I just upgraded my Netbox server from v2.7.6 to v3.4.8. This is just a record of what I did in case anyone want to know how I did it.

Environment

• The source v2.7.6 server is an Ubuntu 18.04 VM. Yes, both are very old.

• The destination v3.4.8 server is an Ubuntu 20.04 VM.

• We have no media, scripts, or reports in Netbox.

• I’m running Virtualbox on my laptop to do the data migrations.

As a warning to everyone, I am not a developer. I am a network engineer who is trying to do some automation stuff. Some of what I’m doing sounds logical to me, but I would not trust my own opinions for production work. I’m sure you can find a Slack channel or Mastodon instance with people who can tell you how to do things properly.

We’ve added stuff and updated stuff, so let’s delete some stuff. “Hey, man…you already did that,” you say? You’re right! When we started creating API tokens based on user/pass, we made sure to delete the token at the end. That means we should all be professional pynetbox deleters, then, right? :)

I’ve been using Netbox for a while now, and, frankly, I can’t live without it. If you’ve never heard of it, it’s a Source of Truth for your network automation tasks started by Jeremy Stretch. I use it to document my networks (hardware inventory, subnets, physical connections, etc.), which provides my automation tasks a place to pull and push all sorts of information like management IPs, rack locations, power connections, network drops…the list goes on. In better words, your automation tools can ask Netbox what the state of your network is, and send it an update if that tool discovers something different. There are plenty of better places to discuss the benefits of a Souce of Truth, so just do the Googles for it.
