Upgrade - no. Unless there's something specific in RHEL4 that you can't
get in RHEL3, keep running what you have.

I look at those on a case-by-case basis. I've just started the install
of another RHEL3 system but I've got 4 servers coming in the next week
or two that will run RHEL4. The RHEL3 system is SAN-connected and I'm
trying to keep it up at the same rev level as a sister system. The
RHEL4 systems are fairly specific handling mostly mail relaying and a
couple of internal applications. They're replacing systems that are
currently running 6.1 and 6.2.

It depends on what you need it to do. If RHEL3 offers you everything
you need, you might wait until after Update 1. I expect some of the SAN
connectivity issues to drag on past Update 1 because of the redesign of
the multipathing stuff.

That is a good deal. I don't know if you can instal RHEL3 on SATA
drives though so that could be one reason to go to RHEL4. Also, the 2.6
kernel handles hyperthreaded CPUs more efficiently than the 2.4 kernel.
The general theory is to decide what you're actually going to run on the
system and then work backwards from there. The answer is going to be
quite a bit different if you're building a desktop with leading-edge
multivideo apps versus a simple mail relay server.
