Migrating Away from Red Hat Enterprise Linux

Some of the information in this article is advanced material we make available as a courtesy. Please be advised that you are responsible for properly following the procedures below. Customer Support cannot assist with these topics.

As of September 22, 2009, we're discontinuing support of Red Hat Enterprise Linux. You can migrate your server's operating system to Cent OS or independently purchase a software license from Red Hat.

If you do nothing, your account will no longer be charged for use of Red Hat, but you cannot update software via the Red Hat Network or call Red Hat for support.

To Purchase a New Red Hat Enterprise Linux License and Configure Your Server to Connect to the Red Hat Network

You can purchase Red Hat Enterprise Linux from Red Hat directly on their site.

  2. Go to the Systems tab in the top navigation bar, then select the name of the old system or duplicated system in the System List.
  3. Click delete system in the top-right corner of the page.
  4. Confirm the removal of the system by selecting the Delete Profile button.
  5. As root at the command line, delete the file (if it exists) /etc/sysconfig/rhn/systemid from your system by running the command:
    rm /etc/sysconfig/rhn/systemid
  6. Run the following command to register your system with the update agent:
    rhn_register
