Upgrading to Red Hat Enterprise Linux

Running an older version of Red Hat® Enterprise Linux®? Transitioning your existing Red Hat Enterprise Linux AS/ES/WS installation to Red Hat Enterprise Linux 5 couldn#39;t be easier.

When a Red Hat Enterprise Linux AS subscription is renewed, it automatically shifts to the Advanced Platform part number, and the additional Red Hat Network entitlements are enabled. These allow management of an unlimited number of guests per server and provide access to the storage virtualization and high-availability components (Red Hat Global File System and Red Hat Cluster Suite).

Subscription changes

Version 5 does not include AS or ES variants. But the underlying subscription limits will persist:

  • ES customers will be supported on systems with up to 2 processor sockets.

  • AS customers will be supported on systems of any size.

Both AS and ES customers will be able to use virtualization immediately and will find that Red Hat Network lets them manage up to 4 guests per server.
