We went from RHEL5 to RHEL6 on our clusters about 2 years ago, we started off with a new machine that went straight to RHEL6 and then the other two existing Intel clusters had separate week long outages and we treated it as essentially as a reinstall of each cluster from scratch. We also transitioned from Torque+Moab to a pure Slurm solution at the same time. It meant a lot of rebuilding of software, but I was actually surprised at how easily it went all up. For a strategy for upgrades, I suspect that's really down to each site as there will be differences in the resources available, the push/pull from old to new plus the good old "if it ain't broke, don't fix it".
