Randy Upgrading versus Reinstalling comes down what need to be done on the nodes . If the nodes are just end points with all application installed at install time and there is no data local to a node the rinstall method is preferred as you get a node in a clean state.
Upgrades is generally more preferred when the application stack is handles by 3rd party application and is not part of the xCAT install process or there is data on local node drive that need to be preserved as an install formats the hard disk and this data will be lost. With upgrades you would want to do a test on one node first in a manner that get to you end point in your example you would benefit from doing a RHELs 6.4 -> RHELs6.5 -> RHELs6.6 so that you do not end up with dependencies issues as packages do change from release to release.
