Upgrade Proxmox VE cluster to a supported version
On our "Atlantic" cluster, we're currently running Proxmox VE 6.4, which is EOL and no longer receives security updates. Furthermore, Proxmox VE 7 is also EOL, so we'll now need to do a two-step upgrade to get to Proxmox VE 8, where we should hopefully be good for another 3 years. Both Proxmox VE 7 and 8 also have a dark theme, which ought to be incentive enough to do the upgrade.
Before upgrading, we probably want to make sure we have solid backups of our VMs and host configuration, as Ceph can be fragile, and we have a lot of data being stored in Ceph.
Instructions for how to upgrade are at the links below:
