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.
