VMware GSX Server Administration Guide

If you plan to use existing virtual machines that have disks in undoable mode,
commit or discard any changes to the virtual disks before you remove the
release you used to create them.
• Resume or power on the virtual machine in the earlier release, shut down the
guest operating system, power off the virtual machine and either commit or
discard changes to the undoable disk when prompted.
• Back up virtual machines.
Back up all the files in your virtual machine directories — including the .vmdk
or .dsk, .cfg or .vmx and nvram files — for any virtual machines you plan
to use under this release.
Virtual machines updated for full compatibility with GSX Server 3 can be used
only with other VMware products beginning with GSX Server 3, Workstation 4
and ESX Server 2, but not under earlier versions of VMware software.
• Back up the GSX Server software.
If you intend to use your older GSX Server software, keep the CD-ROM or ESD
installation package handy, or else back up the drive on which GSX Server is
currently installed.
If you need to install the software on the same computer where you now have
an earlier version installed, make sure you back up the current installation and
the virtual machine files so that you can restore them later.
• Uninstall any existing version of GSX Server.
If you have GSX Server installed, you must uninstall the previous build before
installing the new version:
• To uninstall a previous version of GSX Server 3 or GSX Server 2.x for Windows
hosts, see
