Can I upgrade my Red Hat Enterprise Linux to Fedora Core (or vice-versa)?

No. Fedora Core and Red Hat Enterprise Linux products are two different platfoms. Changing from one to the other requires a fresh install of the operating system.

Back-up essential data and configuration files before the install and restore them from backup when finished.

Note: Red Hat Technical Support's Service Level Agreement does not include Fedora Core Support and will only assist in troubleshooting issues with Red Hat Enterprise Linux.
