This article guides you through the process of determining whether the hardware version of your virtual machine is up-to-date for the version of VMware Fusion that you are using. This resource also explains why a virtual machine created with VMware Fusion may not power on in another version/copy of VMware Fusion.

VMware Fusion powers on a virtual machine with a virtual hardware version that is lower than what it supports, but functionality may be lost. With lost functionality, menu items/settings related to virtual machine operations gray out and become unavailable.

Note: If a virtual machine is created in a different VMware product (for example, VMware Workstation) that supports a virtual hardware version, and it is then migrated to a version of VMware Fusion that does not support this level of virtual hardware, it does not power on. For example, Fusion 1.x does not power on virtual machines created in Workstation 6.x or 7.x. For information on virtual hardware versions for other VMware products, see Virtual machine hardware versions (1003746).

To upgrade the virtual hardware:

In Fusion 13.x, 12.x, 11.x, 10.x, 8.x, 7.x, 6.x, 5.x, and 4.x:

1. Shut down the virtual machine.
2. In the Apple menu bar, select Virtual Machine > Settings.
3. Select Compatibility.
4. Select the hardware version that is compatible with the VMware product you want to run the virtual machine with.

In Fusion 3.x and earlier:

1. Power off the virtual machine.
2. Go to Virtual Machine > Upgrade Virtual Machine.
   
   Note: If the Virtual Machine menu only has an option that reads Downgrade Virtual Machine, then your virtual machine has the highest hardware version supported by that version of Fusion.

To downgrade the hardware version of a Fusion virtual machine, see Downgrading from Fusion 4 to Fusion 3 (2005310) or Downgrading from Fusion 3 to Fusion 2 (1020246).
