23.2. Upgrading Your System

The Upgrade Examine screen appears if you have instructed the installation program to perform an upgrade.

Note

If the contents of your /etc/redhat-release file have been changed from the default, your Red Hat Enterprise Linux installation may not be found when attempting an upgrade to Red Hat Enterprise Linux 5.

You can relax some of the checks against this file by booting with the following boot command:

linux upgradeany

To perform an upgrade, select Perform an upgrade of an existing installation. Click Next when you are ready to begin your upgrade.

To perform a new installation of Red Hat Enterprise Linux on your system, select Perform a new Red Hat Enterprise Linux installation and refer to Chapter 4, Installing on Intel and AMD Systems, Chapter 12, Installing on IBM System i and IBM System p systems, or Chapter 17, Installing on IBM System z Systems for further instructions.
