Upgrade to v. 7

[Matus]

Hi,
I have cluster with 3 nods. Is it possible and safe to upgrade 1. node to v. 7 and migrate to it containers from nodes v. 6.x ?
And then do it for other nodes?
Or I have to do backups and restores after upgrade?

Yes, this is the recommended way, to upgrade the nodes one by one. After node A successfully upgraded to PVE 7 latest version, you have to reboot it then migrate the VMs/CTs to it, and do the same steps on node B, etc…

Or I have to do backups and restores after upgrade?

And yes, we recommend having a valid backup for VMs, and PVE configs as well.

Thank ypu.
It means, that it is possible to have mix of v6 and v.7 nodes in one cluster.

I assumed that you will upgrade all cluster nodes.

Yes it's possible, but it's not recommended to mix of PVE version on a cluster, specially if the Cluster manages HA
