why not keep the FC6 server running while you set up the new server with CentOS or Debian. that way you have all the time you need, have your server up and migrate to a well supported server OS in one big action.
FC6 is unsupported for ages now, so even if you could I really wouldnt migrate it to a different server anymore. besides running an installed OS on different hardware in a live situation is asking for trouble imho.
