Changing the Protection Level for a Virtual Machine (HA or FT)

You can change the protection level of guest VMs from high availability (HA) to fault tolerance (FT), or vice versa.

Note: You cannot change the protection level or preferred node of an unprotected VM. For more information, see Unprotected Operation.

To change the protection level

On the Virtual Machines page, select a stopped VM (marked "stopped" in the Activity column). (See Shutting Down a Virtual Machine for information about stopping a VM.)
In the bottom pane, click Config to open the Reprovision Virtual Machine wizard.
On the Name, Description and Protection page, select the HA or FT button.
Continue clicking through the wizard pages to the last page. Press Finish and then OK (if the reconfiguration was successful).
