Hi, I tried testing the CentOS upgrade rpms and documentation, by trying to upgrade a (freshly installed) CentOS 6 virtual box image to CentOS 7. I tried following the steps described at http://wiki.centos.org/TipsAndTricks/CentOSUpgradeTool as closely as possible. There was just one minor hiccup. I had to disable gpgcheck after running, centos-upgrade-tool-cli because of the attached error. Apart from that, everything went smoothly, even though I had the EPEL repo enabled.
