RedHat AS 3.2 to 3.4 upgrade procedure
requirement to upgrade our RedHat Linux AS 3, update 2 machine to Redhat Linux AS 3, update 4. Is there a procedure to perform this upgrade with out using the RHN update procedure. Have the RH AS 3 update 4 cd images, but, when booting from the cd's, it appears that the install, though mentioning an upgrade procedure, wants to wipe the original AS 3.2 from the machine, and start over to apply update 4.
What sucks is the boss does not trust the RHN update procedure, which might mean I would lose all the original configurations performed on the 3.2 machine.
And, side question, is there a command to print the os patch level ?
greatly appreciate feedback.
Re: RedHat AS 3.2 to 3.4 upgrade procedure
RHN up2date works just fine. Update 4 is not much more than patch releases. This is *not* Red Hat Enterprise Linux 4 that was just released - for that, you can't use up2date to do the upgrade.
Don't forget that all up2date does is give you the last of updates it will apply (you can see this with up2date -l), download the rpms, and then apply those. You can, if you want, download the rpms manually and instal them (or a subset of them). It's a lot more work for the same gain though.
