Scenario: A Citrix Administrator used the versioning feature of Provisioning Services to test changes made to a vDisk. After a successful test, the version is
promoted. All users are using the latest production version. Over time, additional versions of the vDisk are created. To conserve space, the administrator decides to
merge all of the versions to a new base version but the Merge option appears grayed out.
Why does the Merge option appear grayed out?

A.
Merging within the Provisioning Service console is only possible for an individual vDisk version.

B.
The vDisk was NOT created with the latest version of the Provisioning Services target device software.

C.
The administrator needs to promote the existing Maintenance Version to Test or Production, after that the Merge option becomes available.

D.
The last production version of the vDisk is locked and used by the Target Devices.
After all locks are removed, the Merge option becomes available.
