Red Hat does not support upgrades from earlier major versions
Although anaconda provides an option for upgrading from earlier major versions of Red Hat Enterprise Linux to Red Hat Enterprise Linux 6, Red Hat does not currently support this. More generally, Red Hat does not support in-place upgrades between any major versions of Red Hat Enterprise Linux. (A major version is denoted by a whole number version change. For example, Red Hat Enteprise Linux 4 and Red Hat Enterprise Linux 5 are both major versions of Red Hat Enterprise Linux.)
In-place upgrades across major releases do not preserve all system settings, services or custom configurations. Consequently, Red Hat strongly recommends fresh installations when upgrading from one major version to another.

To be supported, you will need to back up your data and do a fresh install of RHEL 6.

If you don't care about that, you can probably just pop in the RHEL 6 DVD and do an upgrade.

from the very very old 5.1 ( never been updated 5 ) to 6.0
NO
will not work

1) download the 6.0 install dvd
2) do a fresh/clean install of 6
3) BUY A LICENSE !!! - a MUST !
4) copy backed up data from a rhel5 KNOWN GOOD back up to rhel6 ( some data will not move over )

Possible to upgrade

I am currently upgrading numerous vm servers from RHEL5 to RHEL6. Your best bet is to download the RHEL6.1 iso and boot your RHEL5 machine from that and at the install menu screen hit esc and type in linux upgradeany. That should take you through the upgrade process.

If you have a paid subscription to RedHat, contact them. They will tell you it is not supported but they still take a look at it. I have a RH engineer looking at my case right now.

I just posted the in-place upgrade steps from RHEL 5.5 to RHEL 6.2 here -> http://www.linuxquestions.org/questi...hel-6-x-34929/
