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
Given how radically the OS changed, I would strongly advice against it. The move from sysvinit to systemd alone is enough to recommend against an upgrade.
So it's not possible under any circumstances?
I suppose anything is possible with enough time and effort, but I strongly recommend against it.
CentOS is a server OS and as such should be used in a manner that provides maximum reliability. An upgrade in general introduces avoidable risk. An upgrade from 6 to 7 would induce far more risk than usual.
Much safe to setup centos 7 fresh and migrate services over in a controlled fashion.
I'm aware and appreciative of these risks. However, given the unique situation I need to address, it's worth spending the time needed to attempt this. If some tweaking, and a moderate amount of head-wall contact is required, that's ok.
If there is any method that provides a reasonable approximation of success, I'd be thankful if you could point me to it.
