From the Options dept.:
Novell has launched a "competitive replacement" program aimed at luring Red Hat and CentOS users to its SUSE Linux Enterprise Server (SLES) product. Through the program, Novell will support customers' RHEL or CentOS servers for up to two years, while the customer migrates to SLES.

The program covers Red Hat Enterprise Linux (RHEL) versions 3, 4, and 5, for up to two years, or the end of their product lifecycle, whichever comes first. It also supports corresponding versions of CentOS, a free, community supported distribution compiled from Red Hat source code.
