personally, I'd do a clean install on the new system, with CentOS 6,
then copy over users from /etc/passwd and shadow, the /home directories,
any other NFS share points, and manually configure any other
applications you might host. I believe you can move an NIS master by
bringing it up as a NIS client, synching it, then promoting it to a
ypserver, then making it the new master (and in fact, if you do this,
you don't even need to manually copy the users via /etc/{passwd,shadow} )
