[ale] Red Hat upgrades?

[Lightner, Jeff]

On rethinking it did seem to me that when I installed a RHEL6 system
there was an option for upgrade.

This page has screen shots showing it.

Haven't done it and won't for the reasons noted but if you want to
try...

By the way they changed the way subscriptions work in RHEL6.  I don't
know the details but you should probably investigate before you upgrade.

So far as I know RHEL doesn't have an upgrade path between major
releases.  You can upgrade RHEL5.4 to RHEL5.6 simply by doing "yum
update" but I don't know of a method to go from RHEL5.6 to RHEL6.0
without doing a reinstall.

Based on experience years ago with a well planned upgrade between major
releases of a commercial UNIX I decided it was never worth the effort
because:
1)  There is always something you didn't plan for.
2)  Much cruft behind from the old release that you're never quite sure
it is safe to remove.
It is much simpler to do a fresh install (ideally to a new machine) and
migrate applications over.   The other benefit to this is there is a
clean backout (i.e. using the old server) if the new environment has
issues.

I think you're looking at a clean install.
