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. -- john r pierce, recycling bits in santa cruz
