I wonder if there are any plans to include a preupgrade option from EL5
to EL6.
Or is the jump too large.

Tom and Chris,
I don't have the reference off hand, but I believe the recommendation of
reinstalling and not upgrading was from RHEL3 to RHEL4 because of the kernel
going from 2.4.x to 2.6.x. It may have been in the release notes. However, it
was only recommended to reinstall, it didn't say you couldn't.

I don't understand this part. You can certainly do 5.0 -> 5.1 style
upgrades "in-place", and you can upgrade between major versions using
boot media (either net boot, CD, whatever) if you wish, no requirement
to format the drive.
According to the Red Hat docs, you can upgrade that way, but it is not a
supported upgrade path. To me, that means they don't test it (or at
least not much), so I can't expect it to work on a production system.
If it breaks part of the way through, or installs a bogus package set,
etc., I'm stuck with a busted system and no path back to a working
system but to wipe and restore from backups.
I'm curious what Redhat documentation says that? Here's a link to some
RHEL5 documentation regarding upgrade:
http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5/html/Installation_Guide/ch-upgrade-x86.html
The first line:
While upgrading from Red Hat Enterprise Linux version 4 Update 4
is supported, you are more likely to have a consistent
experience by backing up your data and then installing this
release of Red Hat Enterprise Linux 5.3 over your previous Red
Hat Enterprise Linux installation.
So what they're saying is that a clean install will give you the best
possible/cleanest experience. That's a true statement pretty much no
matter the OS, but upgrading is supported. Obviously they can't be 100%
sure that you might have a setup which, someway, somehow, breaks
anaconda from being able to complete an upgrade, as there are infinite
number of combinations of hardware, but they test it and it generally
works and is supported.
Later,
Tom
