Well I usually do rolling updates, (i relocate the services to other
nodes, and update one node, then restart it and see if it joins
I start with test cluster, follow the path with clusters with lower
priority and finish with high priority clusters. If I find some
problems somewhere down the path, I slow down and debug. So far, no
problems at all. (5.1 -> 5.2, 5.2 -> 5.3, 5.3 -> 5.4).
Only problem I encountered so far was when CentOS published part of
cluster suite from 5.4 into 5.3 repositories...
