You could also attempt to migrate from RHEL to one of the rebuilds like
Tao, CentOS, or White Box Linux.  I've never tested this and don't know
what issues you will run into.  It probably shouldn't be tried for
people who want it "to be very basic for dummies".

It is not so hard; the process has not changed much. First read and heed:
	http://www.owlriver.com/tips/centos-31-ex-rhl-9/

Review the Ceontos and Caosity project websites, and decide if the project has what you need.
	http://centos.caosity.org/ -and-
	http://www.caosity.org/

And once your backups are done, basically:

1.	Get rid of a possible conflict
		rpm -e redhat-release


2.	Fetch the Centos signing key into RPM
		rpm --import \
http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-3


3.  	Install yum:
		rpm -ivh \
http://mirror.centos.org:/centos/3/os/i386/RedHat/RPMS/yum-2.0.8-1.centos.7.noarch.rpm


4.	Edit the yum.conf to contain:

[base]
name=CentOS-$releasever - Base
baseurl=http://mirror.centos.org/centos/3/os/$basearch/
gpgcheck=1

#released updates
[update]
name=CentOS-$releasever - Updates
baseurl=http://mirror.centos.org/centos/3/updates/$basearch/
gpgcheck=1


5.	Do the first part of the cutover:
	yum -y upgrade rpm glibc
	rpm -vv --rebuilddb

6.	Do a reboot, to set the new libraries


7.      Do the rest of the cutover:
        yum -y upgrade
