Hello Leandro, If you are under Proxmox 6.4, you cannot move "accidentaly", by software upgrades, to 7.0. Because 6.x is based on Debian 10, and 7.x on Debian 11, so you have to change the repository to point to the newer release. What I do personnaly is to test the upgrade on a test cluster, to see how it works. I have an old server on which I setup a nested proxmox ve cluster with three small VMs. I test the upgrade process on this nested cluster, before applying it to production cluster. For your produxtion cluster, you should have backups of your VMs (for example on an NFS storage). It would be indeed a good thing to have à third host to have a minimum cluster with quorum. Good luck !
