44 Appendix C. Upgrading Your Current System
lems. Otherwise, the upgrade procedure takes care of these dependencies, but it may need to install
additional packages which are not on your system.
Depending on how you have partitioned your system, the upgrade program may prompt you to add an
additional swap file. If the upgrade program does not detect a swap file that equals twice your RAM,
it asks you if you would like to add a new swap file. If your system does not have a lot of RAM (less
than 128 MB), it is recommended that you add this swap file.
C.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 4.
You can relax some of the checks against this file by booting with the following boot command:
linux upgradeany
Use the linux upgradeany command if your Red Hat Enterprise Linux installation was not given as
an option to upgrade.
To perform an upgrade, select Perform an upgrade of an existing installation. Click Next when you
are ready to begin your upgrade.
To re-install your system, select Perform a new Red Hat Enterprise Linux installation and refer to
http://www.redhat.com/docs/wp/ as well as Chapter 2 Installing Red Hat Enterprise Linux for further
instructions.
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 2 Installing Red Hat Enterprise Linux
for further instructions.
C.3. Upgrading Packages
At this point, there is nothing left for you to do until all the packages have been upgraded or installed.
C.4. Upgrade Complete
Congratulations! Your Red Hat Enterprise Linux 4 upgrade is now complete!
The installation program prompts you to prepare your system for reboot.
