Oh, you want to upgrade specific packages from those in 2.1 to those
used in 3.0?  Yes, you'll have some major problems--mostly having to do
with needed prerequisites.  If you are going to update 2.1, you need to
get an update entitlement from Red Hat (they're not free), then you can
use up2date to keep the machine current with the latest 2.1 stuff.

If you want to upgrade from 2.1 to 3.0, do what I said above.  Remember,
NONE of Red Hat's "Enterprise" Linux releases (ES, AS, EL, WS) are free.
You get 1 year of free updates when you buy, but after that, you must
renew the update entitlement.

If you want free Linux, you have a number of choices.  The closest to
Red Hat Linux are Fedora Core 1 (FC1) and Fedora Core 2 (FC2).  FC1 was
_going_ to be Red Hat Linux 10 before they decided to go the "pay to
play" route.  FC2 is the latest release (using the 2.6 kernel and
X-Org's X Windows implementation rather than XFree86).  I use it a lot.
Due to the 2.6 kernel, there are fewer drivers available for oddball
hardware but this should improve over time.  It doesn't bother me as
I'm considered to be something of a geek.

There are other free ones such as Mandrake (more geek-oriented), Debian,
GenToo and a whole bunch of others.  There is a free version of AS3 out
there called "WhiteBox" which is built from Red Hat's AS/ES3 source
RPMs.  I've never used it and don't know how easy it is to install or
upgrade from AS2.1 to it, but once it's up, it's essentially ES/AS 3.0.
