I have a PVE 8.4 installation that I want to delete and clean install 9.0. Not that I am afraid to do an upgrade (well, maybe a little) but moreso because I installed 8.4 as a test and did a lot of things that you're not supposed to do with it, like installing packages and other mucking around at the host level. So I'd like to nuke the host and clean install PVE 9.0. The only problem is I created several VMs that I'd like to keep. Can I copy or back them up to a different drive before I delete the host, and then restore them later? If you haven't guessed yet I am a PVE beginner.
