.... I would think backing up the Hyper-V Virtual Machine in its entirety then restoring it would preserve Amazing Charts' certification of the server. However, I have yet to test that.

We use RHV and KVM, but functionally I expect it will be the same from a virtualization perspective.
We clone/snapshot before we do an upgrade, and that gives us an ability to revert seamlessly when an upgrade goes sideways, but it also allows us to run an upgrade on the clone for a practice to experiment with prior to deciding if they want to do the upgrade, or to test a restore.
Virtualization [and containers] is where technology is headed, and I know certain Docs on the board and elsewhere who have been using Linux servers and virtualization for years. Did I mention free and high performing?
