Can someone tell me if this is correct?
1. rpm -qa kernel\* # to get installed kernel versions for baseline
2. up2date -l # Lists what is available...
3. up2date -u # install updates
4. up2date-config # hit 5 and change to yes for enabling rollbacks
5. up2date -f kernel<name> # this is to get around bug that does not download kernel updates
Nope...mainly because RHEL4 is no longer supported as of February 2012, and the repositories won't work. You should be able to call Red Hat support, since you're paying for RHEL, and get them to help you.
The latest is 6.4...even *IF* the up2date command still worked to update old servers, you'd not be able to jump major versions. Contact RHEL support.
