Upgrading from one major release version to another, for instance 4 to
5, is not "supported" by Red Hat. It can be done but you are on your own
and usually it is done via booting off install media or similar. Also
there is no real easy method of a rollback aside from a backup/snapshot.
I have done this but I strongly recommend you opt for a clean install.
It will be less of a headache in the long run. Best build a new system
and set it up as close as possible to the other then migrate via
something like a DNS/hostname change.

Hi All,
I want to upgrade the RHEL 4 server . This is production machine. I
would like how can I rollback the changes if something goes wrong? I am
going to upgrade the RHEL server by running command "up2date -uf".
I have below version installed right now:
"Red Hat <http://it.toolbox.com/trd/95/7/9824/> Enterprise Linux ES
release 4 (Nahant Update 8)". I tried to run below command on staging
server but i came to know that it is not supported in this version.
Please let me know is there any procedure to do rollback the installed rpm.
up2date --list-rollbacks
This feature is deprecated and no longer functional
