== HOWTO: Convert CentOS 7 to RHEL 7 ==

== Getting Started ==

Before starting, note that the system must have a minimum of 5GB free on the root partition.

First, you will need to add the repos to install convert2rhel: 
	<code>sudo curl -o /etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release https://www.redhat.com/security/data/fd431d51.txt</code>

	<code>sudo curl --create-dirs -o /etc/rhsm/ca/redhat-uep.pem https://ftp.redhat.com/redhat/convert2rhel/redhat-uep.pem</code>

	<code>sudo curl -o /etc/yum.repos.d/convert2rhel.repo https://ftp.redhat.com/redhat/convert2rhel/7/convert2rhel.repo</code>

Next, install Convert2RHEL:

	<code>sudo yum -y install convert2rhel</code>

Grab the activation key:

<code>curl --insecure --output /usr/share/convert2rhel/subscription-manager/katello-ca-consumer-latest.noarch.rpm https://phobos.auburn.edu/pub/katello-ca-consumer-latest.noarch.rpm</code>

Next, set the key in /etc/convert2rhel.ini:

	<code> [subscription_manager] </code>
	<code># password = <insert_password></code>
	<code>activation_key = RBDLibrary</code>

== Running the conversion ==

First, we need to stop several services. You should also stop any other services that may cause data corruption or conflict, i.e. mysql:

	<code>sudo systemctl stop lockss</code>
	<code>sudo systemctl stop cisco-amp</code>
	<code>sudo systemctl stop firewalld</code>

Next, we just need to run the converter. If the steps above were followed, it should go through with minimal user interaction, only requiring approval on a few prompts.

	<code>sudo su</code>
	<code>convert2rhel –org OIT</code>

After the conversion completes and the system reboots, verify the OS:

	<code>cat /etc/os-release</code>
