After migrating a site from a self hosted network controller to a new Unify Cloud Key, I found myself in an annoying position: not being able to remove an old VTI VPN (from the previous configuration). The UI just didn’t offer this option like it should and actually does for other networks and VPNs. Searching the wild wild web didn’t help either, so I had to be creative.
But first let’s roll back a bit in time to better explain the issue: right after importing the site configuration, I had two sites configured. The “default” and “SITE2” sites. My newly imported “SITE2” site wasn’t the default one and this was an issue. I had to change it manually using this CLI technique because the UI doesn’t allow it.
So, based on the above mentioned technique, I succeeded to remove an old network from the settings, where the UI wasn’t competent.
SSH to your Cloud Key/Docker/Server wherever the Unify Network Controller is hosted. Then start the mongo DB CLI with mongo --port 27117.
Switch to the Network Controller database with use ace then get the list of networks with db.networkconf.find(). You should get something like this:

You default network should be the imported network now.
