Be curious myself as to what info you come up with on the "upgrade via ISO" and "SATA" support questions you posed.
Hopefully someone on the list will help you out with a reply to the list.

Cutting straight to the chase:
When, if ever, does the installer offer an option to upgrade an existing installation, rather than wanting to reformat the disks?
More details than you may want:
I recently acquired a new PC chassis, with no operating system but with a Serial-ATA disk (which I was not expecting when I ordered it). I set the BIOS for legacy IDE mode and installed RedHat 9, then attempted to upgrade the kernel to add SATA support, without much luck.
Searching for the SATA driver modules I found CentOS and decided to try it. I downloaded the three ISO images to another PC, burned CDs, and set about to upgrade my RH9. However, the installer never offered me the option of upgrading (keeping my existing filesystems) -- no matter what steps I tried using when starting the installer, by the time it got to the page for disk partitioning it always wanted to start from scratch and blow the existing partitions away.
I finally concluded that I hadn't put anything important on the disks during my struggle with RH9, so I went ahead with the clean install. Everything is working nicely at this point, so thanks for that.
However, there are some other RH9 systems around the office that may need to be upgraded at some point, and they definitely can't be wiped clean in the process. Is there a way to upgrade from RH9 to CentOS?
Any remarks about upgrading from even older RedHat releases?

For the record, CentOS 3.1 supports SATA just fine.
My only question is about the upgrade option during installation.

Yes ...
It is my understanding that there is no upgrade path available from Red Hat 9 to Red Hat Enterprise Linux 3, so I doubt you will find anything of that nature in the CentOS installer either.
It does seem a little odd since RH9 is so compatible with RHEL3. You should be able to find more information at redhat.com.

The CentOS installer is simply a straight rebuild (with all appropiate trademark changed applied) of the RH supplied anaconda installer, without extension to support upgrades (as RH did not have that support present in their version)
Intentionally, there is no separate CentOS installer; the 'yum' upgrade method (which honors dependencies, and will remove obsoleted packages) will work, with some intervension, as indicated in my prior post.
The cAos project installer, 'cinch', could probably be adapted to do installations of CentOS, but it is not clear spending the release engineering effort to do so has sufficient demand to warrant the effort. That said, of someone wants to take a run at doing so, I am certain we can find a place for a stable maintainable effort in the mirror tree. ;)

The Taroon, and some other RH mailing lists have discussed this; some of the transition paths for an upgrade from RHL to RHEL are untested; anaconda does upgrades (and installs) essentially with RPM in a --force --nodeps mode, and so (as it is working from a closed universe of packages) RPM can assume that the packageset is consistent and complete
By not directly supporting the RHL to RHEl path, Red hat has avoided the need to do much release engineering. A win for them, and probably economically rational.

I do understand this. My apologies for the confusing wording.
