Description:
There doesn't seem to be any real (step-by-step) documentation on how to perform a
rolling restart/upgrade within a cluster setup or in which order the different node types
need to be started on a cluster software update.

Information on which version is compatible to which is also missing although
critical as even minor releases may not be compatible to each other.

How to repeat:

Suggested fix:
