To upgrade from version 1 or 2 to version 3, you must have the full VMware GSX Server 3 product.

If you used the tar installer to install your current version of GSX Server, and you plan to use the tar installer for the new version, the only special step you need to take is to make sure the directory to which you plan to untar the tar archive does not contain any files from a previous GSX Server tar installation. You do not need to uninstall the older version. Just follow the installation instructions under Installing VMware GSX Server on a Linux Host.

If you used the RPM installer to install your current version of GSX Server, you need to uninstall the software before you upgrade to the new version. See Uninstalling GSX Server on a Linux Host.
