If you don't use SELinux just copying over should be fine, mostly. However, 
I wouldn't recommend it, apps sometimes spread their files a bit so you may 
miss one or two ... Also, your rpm/yum database is not in sync then. What I 
usually do (on server machines) is reinstall all software that is really 
needed (which usually results in less software getting installed than on 
the old machine ;-) and then replace their configuration files with the old 
ones. Home directories, MySQL databases etc. can just be "carried over". 
And you can carry over users by just adding them with cat or a text editor 
to the passwd/shadow/group/gshadow files.
