Convert RHEL 6 to CentOS 6

If you are using RHEL 6.x and you want to move to the free CentOS 6.x, it is very easy to do this migration.

Open terminal and enter the following commands by order:

# yum clean all

- Create CentOS directory

 # mkdir ~/centos

- Cd CentOS directory

# cd ~/centos

- Download the packages

# wget http://mirror.centos.org/centos/6.0/os/x86_64/RPM-GPG-KEY-CentOS-6
# wget http://mirror.centos.org/centos/6.0/os/x86_64/Packages/centos-release-6-0.el6.centos.5.x86_64.rpm
# wget http://mirror.centos.org/centos/6.0/os/x86_64/Packages/yum-3.2.27-14.el6
.centos.noarch.rpm
# wget http://mirror.centos.org/centos/6.0/os/x86_64/Packages/yum-utils-1.1.26-
11.el6.noarch.rpm
# wget http://mirror.centos.org/centos/6.0/os/x86_64/Packages/yum-plugin-fastes
tmirror-1.1.26-11.el6.noarch.rpm

- Now enter the following commands by order to import CentOS key, install the downloaded packages and to upgrade to CentOS 6.x

# rpm –import RPM-GPG-KEY-CentOS-6
# rpm -e –nodeps redhat-release-server
# rpm -e yum-rhn-plugin rhn-check rhnsd rhn-setup rhn-setup-gnome
# rpm -Uhv –force *.rpm
# yum upgrade

Now reboot and enjoy.
