Gnome/KDE can not be upgraded in place, at least not without removing and then reinstalling Gnome/KDE. Here is the wiki page on the upgrade tool: http://wiki.centos.org/TipsAndTricks/CentOSUpgradeTool You can do things like: yum grouplist Then remove groups like Gnome and KDE, then upgrade, then groupinstall Gnome or KDE after the upgrade. I have run upgrades on several test VMs and they did upgrade, but I don't think I would upgrade anything in production in place. And this is not just advise I would give for CentOS .. I would also not upgrade anything in place (Not Windows from XP to Win7 to Win8 .. not any version of Linux from one major version to another, etc.). But thats just me ... I find it much smoother in the long run to reinstall and move data. Thanks, Johnny hughes
