Mix Proxmox 4.2 with 4.4 inside cluster.

[sebastianj]

Hi,

Haven't found exact answer.
Situation: 5 node cluster running 4.2-2/725d76f0 and I want to add 4 new nodes.
Don't have 4.2 ISO, and it's not available for download.

Is it safe to install 4.4 on these new boxes and let them join the cluster?

Regards.

Hi,

Why you can't update the 5 nodes?

 

[sebastianj]

Critical VM's are running on these 5 nodes.
Can't reboot them now. Have to schedule maintenance etc.
Would like to avoid it for now.


Regards.

Theoretically it should work and make no problem, but we do not test this kind of setups.
The upgrade node by one node is always possible when it comes to version bumps.

OK,thanks.
Then it probably means I have to upgrade first existing nodes to be on safe side.

...or maybe somebody can provide me with iso for 4.2 ?
