Using Current to update RH version?

I was wondering if it is possible to use Current to update the version
of Red Hat that you are running.  For example, I am running 7.2 on a lot
of servers.  Sometime before the end of the year, I will need to update
them to a newer version if we are going to keep using Red Hat's errata
(I'm not sure what we would update to at this point since RH 8 is
currently scheduled for 12/31/2003 end of life as well).  The bulk of my
servers are remote (several hours drive away) so I am looking for a
solution that will work across a network.  Any thoughts?

Thanks a bunch!
