I wold like to upgrade a cluster of 3 nodes running proxmox 2.x (originally this was a 1.x cluster).
I cannot stop all running vm (openvz and kvm) for the time necessary to upgrade the cluster.
Can I upgrade one node at a time?
What issues might arise when running during the upgrade process, when there will be a mixed environment of 2.x and 3.x nodes?
I did another upgrade (non critical) on a two node cluster, where I shut down all containers (no kvm there) and I seem to remember that the 2.x and 3.x nodes were seeing each other, altough I did not try any operations on both until the upgrade was finished.
Thank you.
