DNF is a replacement for Yum that will probably be in a future RHEL 
release, but is not used by any RHEL/CentOS yet.

the only sane way to upgrade C5 or C6 systems is to bring up a clean 
install of C7, configure new packages to suit your requirements, and 
import your data.   I prefer doing this with a new server or VM, rather 
than trying to do it on the existing server, once the applications are 
migrated, then I'll redeploy or retire the old server.
