Upgrading cluster from 6 to 7 by reinstalling on new nodes

[Spiros Pap]

Hi all,

I would like to upgrade my cluster from 6 to 7 and at the same time I would like to upgrade the hardware (replace the servers with new ones). Now, I have 3 nodes with pve6.

I am thinking of installing the 3 new servers with pve7, adding them to the cluster and then removing the old ones (add one, remove one, so I always have a quorum).

So, is it possible to add a pve7 node to a pve6 cluster? and then migrate the loads?

Thanx,
Sp

Good morning,

So, is it possible to add a pve7 node to a pve6 cluster? and then migrate the loads?

Yes. As I understand it: migration of machines from the old to the new machines will work. But migrating them back might/will fail. So plan your schedule and sequence of migration good.

Please make sure to read https://pve.proxmox.com/wiki/Upgrade_from_6.x_to_7.0 first, even though you don't go the local in-place-upgrade path.

Good luck
