>>Quick questions - can 3.4 nodes coexist with 4.0 nodes on a cluster?
3.4 nodes will not see 4.0 nodes. It's possible to upgrade all nodes to jessie/proxmox 4.0, at the same time, without reboot host. (and without stop the vms) Then live migration is possible. (and reboot host when it's node) I have sent a mail some months ago about it, but I need to test it again. ----- Mail original ----- De: "Lindsay Mathieson" <[email protected]> À: "pve-devel" <[email protected]> Cc: "proxmoxve" <[email protected]> Envoyé: Mercredi 7 Octobre 2015 01:37:08 Objet: Re: [pve-devel] Proxmox VE 4.0 released! Woot! and Wow! Quick questions - can 3.4 nodes coexist with 4.0 nodes on a cluster? I did see that you can't live migrate VM's from one to the other.
