If a customer who has purchased a single VM instance of ClearPass wants to address the issue of redundancy by taking a snapshot of the installed and configured machine - will there be any issues experienced when the snapshot is brought up on a different piece of hardware. The scenario might be two separate datacentres, I am worried about the license still being valid etc.

I have a very similar problem. We cannot afford to buy two clearpass licenses. We have a VMware setup with High Availability. With regular backups/snapshots to guard against software issues, and VMotion to move the VM to another server if neccessary do we really need redundant Clearpass VMs?

Currently we would be using ClearPass for just wireless. To our instituion wireless is still a "nice to have" not mission critical. If we went down for minutes/hours it would be an inconvience.
When we start using ClearPass as our NAC for wired and wireless we will be forced to run a second ClearPassVM as then it would be a necessity.
I guess my question is more along the lines of "Does clearpass require two instances to run or can it run as a single unit?"
and it appears the answer is yes, but it's not best practice.
