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
