Hello,
I moved the Virtual Machine on which our License Server is installed from Ubuntu-KVM to VMware.
In the process the "hardware" changes prompted the ArcGIS 10.2.2 License Server to throw a fit.
Luckily I still have the old system. I changed the name and the IP of the new VM, restarted the old machine and deauthorized a portion of my licenses from it.
The idea was that I would then reauthorize those licenses on the new machine and make sure everything worked before moving everything to the new machine (I have users that are using the license server, so I cannot keep it offline for too long).
