When You Remove Version 2 Or 3 And Install Version 4 - VMware 4 User Manual

VMware Workstation 4 User's Manual
42
If you have an existing virtual machine that has multiple virtual disks and the disks are
in multiple modes, the simplest approach to upgrading is to convert all the disks to
persistent mode.
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 any undoable mode disks when prompted. Then open the configuration
editor and change all disks to persistent mode. After you upgrade to VMware
Workstation 4, you can use the snapshot feature to preserve the state of a virtual
machine and return to that state at a later time. For more information on the snapshot
feature, see Using the Snapshot on page
If you need to preserve special functionality that requires disks in multiple modes,

Back Up Virtual Machines
As a precaution, back up all the files in your virtual machine directories — including
the .vmdk or .dsk, .vmx or .cfg and nvram files — for any existing virtual
machines you plan to migrate to VMware Workstation 4. Depending on your upgrade
path, you may not be able to run your virtual machines under both VMware
Workstation 4 and your previous version of VMware Workstation.
Virtual machines created under Workstation 2 must have their virtual hardware
updated before they can run under Workstation 4. Once they are updated, they
cannot be run under Workstation 2.
You have a choice with virtual machines that you created under Workstation 3 or
updated to use the Workstation 3 virtual hardware.
• You may update these virtual machines for full compatibility with Workstation 4.
In that case, the virtual machines can no longer be used under Workstation 3.
• You may choose not to update the virtual hardware. In that case, you can run the
virtual machines under both Workstation 3 and Workstation 4, but you will not
have the benefits of the new virtual hardware provided by Workstation 4. Other
Workstation 4 features will not be available. For example, you cannot take a
snapshot or revert to the snapshot while the virtual machine is running; you
must power off before taking or reverting to the snapshot.
