Upgrading by joining a PVE 3.4 with a PVE 5 node and then (live) migrating *cannot* work, if you planned to do so. PVE 3.4 uses quite another cluster communication stack (corosync) as PVE 4.0 and newer, so they cannot see each other. See: https://pve.proxmox.com/wiki/Upgrade_from_3.x_to_4.0 For other upgrade alternatives. _______________________________________________ pve-user mailing list [email protected] https://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user
