No, please do not try that! It will not work.

OK, thanks!

thanks for that answer!
so upgrade of Cluster should be done at once?
another solution to upgrade existing cluster?

Proxmox v4 will use corosync v2 (the software that setup the cluster), which is not compatible with corosync v1, used previously.

See :

So indeed, cluster upgrade will certainly be done at once.
