[PVE-User] In-place upgrade and clusters...

[Marco Gaiarin]

I've upgraded some standalone PVE installation with 'In-place upgrade'
method:
	https://pve.proxmox.com/wiki/Upgrade_from_4.x_to_5.0#In-place_upgrade
without a fuss.

And in this page the note:

	If you run a PVE 4 cluster it's tested and supported to add a PVE 5 node and migrate your guests to the new host.

seem confident to me that the answer to my answer is 'yes'... but...


Upgrading a cluster, can i upgrade node by node, migrating VMs/CTs to
other nodes, without troubles if the source node and the target node
run different PVE versions (latest 4.X and latest 5.X)?

Or i've to shutdown all the VMs/CTs and upgrade all the cluster at the
same time?


Thanks.
