if you want to do the "normal" thing with a CD-boot-upgrade, no,

that's one way, the easier way is to either use apt or red-carpet to
upgrade your distro. with red-carpet, fiddle with
/etc/redhat-release, apt has dist-upgrade, I think. I've upgraded
two machines from 7.0 -> 7.2 with red-carpet, but I'd advice you to
set off a day with this, even if you get the rpms from somewhere
I did it as follows: grab the rpms from RH7.2, with the updates,
from a local mirror, and dump them to /var/cache/redcarpet, then
fiddle with /etc/redhat-release (feel free to install the rpm
"redhat-release"), then run red-carpet. things will break and fail
now and then, fiddle.
these days I have a RH7.2-box that has an uptime of about 240 days.
