Has anyone ever tried to mass replace installed RedHat RPMS with their equivalent CentOS versions or vice versa?
I was thinking of generating a list of all packages and then running RPM or yum with a 'replace' option.
The reason for doing this: Years ago I was tasked with building a RHEL4 system. Budgeting, time constraints, the lunar cycle, etc.., prevented the purchase of an equivalent development environment. So CentOS was used for the development/test system. It sufficed for several years. Now I need to make them as close to identical as possible which means registering the development system in RHN and making it "standard".
I've seen posts that RHEL -> CentOS is at least possible. That is, take a RHEL system and get it to update via YUM and CentOS repositories. I have not seen the reverse, however.

you might want to speak with your Red Hat support / sales guys as well, going down that route might cause them to get upset ( or not be liable for support )

:) Yes, that is a concern. For good or bad, I don't use their support offerings too often. Their turnaround time is 24 hours, and just about every technical question I've had has been much more thoroughly dissected here on this list. The switch to an official RHEL4 is mainly for procedural compliance. I.e., bring it under Satellite control so that we can manage patches and generate reports. Luckily it is a VMWare machine so my intention is to clone the CentOS image, do all the conversion work, then attempt to register it.

Holy heck, that looks very much like what I'm trying to do.. I'm running an CentOS4/RHEL4, but that's a lot of useful information.. Thank you..
