I have a testing server that was running RHEL 5.2 (x86_64) but its RHN entitlement ran out and I wanted to upgrade it to CentOS 5.4. I found a few tips online about how to do that, but they were a little dated so here are updated instructions showing the steps I took:
yum clean all mkdir ~/centos cd ~/centos wget http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5 wget http://mirror.centos.org/centos/5/os/x86_64/CentOS/centos-release-5-4.el5.centos.1.x86_64.rpm wget http://mirror.centos.org/centos/5/os/x86_64/CentOS/centos-release-notes-5.4-4.x86_64.rpm wget http://mirror.centos.org/centos/5/os/x86_64/CentOS/yum-3.2.22-20.el5.centos.noarch.rpm wget http://mirror.centos.org/centos/5/os/x86_64/CentOS/yum-updatesd-0.9-2.el5.noarch.rpm wget http://mirror.centos.org/centos/5/os/x86_64/CentOS/yum-fastestmirror-1.1.16-13.el5.centos.noarch.rpm rpm --import RPM-GPG-KEY-CentOS-5 rpm -e --nodeps redhat-release rpm -e yum-rhn-plugin yum-updatesd rpm -Uvh *.rpm yum -y upgrade # edit /etc/grub.conf to point to correct new kernel (with Xen, in my case) shutdown -r now
It has worked well so far.

I'm happy to hear that it's working so far, but I think the more pressing question is: does it Just Work?
How about migrating from CentOS to RHEL? Do you have steps to share? Thanks in advance.
