Hi All Is it possible to upgrade from CentOS 6.7 to CentOS 7? I see there is some attempt at an upgrade tool available, but it's apparently broken: https://wiki.centos.org/TipsAndTricks/CentOSUpgradeTool Would anyone be able to recommend a manual upgrade procedure to upgrade a minimal CentOS 6.7 system to one or other version of CentOS 7? Many thanks in advance, Traiano
