I manage several Fedora 14 servers. They was not upgraded due to several reasons (systemd unreliability, K12LTSP support absence), some newer packages I was building & updating manually, some other (OpenOffice, Mozilla) was possible update from projects binaries. Now I consider the options to migrate them to Centos 6, possibly the easiest possible way. What I'd like is some as yum configuration files replacement of those from Fedora with files from Centos - and then simply do "yum update". Has anyone tried to do a similar migration? What procedure would you recommend?
Unfortunately the version numbers of many things in Fedora 14 are greater than those in CentOS 6.
I have done this migration, for a desktop user, but I did it with a reinstall (the user has a separate /home filesystem). Most things worked fine, but that was a desktop, not a server.
For that matter I did this migration on my own box not too long after CentOS 6 was first released; but, again, that's a desktop application and not a server. You'll have to check your server packages' versions in detail and see what may be downgraded by the migration.
Since many packages have a greater epoch-versions-release string in F14 than they do in CentOS 6 many packages probably would not get up/downgraded properly.
