The installation process for Red Hat Linux 5.2 includes the ability to upgrade from prior versions of Red Hat Linux (version 2.0 and later) which are based on RPM technology. Upgrading your system installs the modular 2.0.x kernel as well as updated versions of the packages which are currently installed on your machine. The upgrade process preserves existing configuration files by renaming them using a .rpmsave extension (e.g., sendmail.cf.rpmsave) and leaves a log telling what actions it took in /tmp/upgrade.log. As software evolves, configuration file formats can change, so you should carefully compare your original configuration files to the new files before integrating your changes.

If you wish to upgrade your Red Hat Linux system, choose Upgrade.

Please Note: Some upgraded packages may require that other packages are also installed for proper operation. The upgrade procedure takes care of these dependencies, but it may need to install additional packages. You will be shown the names of the required packages, and you may then decide to install them or not. You should install all such packages; otherwise, some of the upgraded packages may not work properly (or at all).
