I think the question relates more to corosync, added the proper group in CC.

I don't know exactly if a rolling upgrade is possible (I may be wrong
on this one) but putting the cluster in maintenance-mode, upgrading
corosync and pacemaker on all 3 nodes and then re-probing for the
resources is a more common upgrade path. If there are no issues on the
reprobe, then you could take the cluster out of maintenance-mode.

Also, do you have a support contract with Suse? I think their support
can help out more on this.
