It might not work, better remove node from cluster, upgrade (better reinstall from zero maybe) and add to a new cluster. Clean. Effectively migrate all VMs from one cluster to another. Or.... try - it might work (I know centos + ubuntu won't work)
But - try one node in the same cluster, then try to live migrate a VM from 22.04 to 24.04, that might work. But not the other way around. Try, you don't lose anything.
