Trying to upgrade from redhat 5.11 to 6.11 and I can not download preparade assist tool from the local repo i created. Tried to enable other repos but its not working.

Any idea how to migrate Red Hat Enterprise Linux 5 to Red Hat Enterprise Linux 6&.

I also need need assistance with steps for creating a kickstart based on your RHEL 5 machine, that can be used for installing a RHEL 7 machine.

Contact Red Hat support, but I doubt they'll even be able to assist, given the age of things. And why install RHEL 7, since it's old as well??

You don't upgrade.

As suggested you should contact Red Hat but be aware that:

Red Hat does not support in place upgrades between major versions and recommends a fresh install.

Version 6 went EOL in 2020, if you have the version 6 installation CD you could enter linux upgradeany at the boot prompt but if anything goes wrong your on your own as far as I know even if you do have a Red Hat subscription.

Trying to do the same from 6 to 7 would probably fail since there were so many changes.

Here is link to making a kickstart file that should be helpful to you.

For RHEL 8, this page is useful: https://access.redhat.com/documentat...perienced-user
