When using MAK on a provisioned vDisk with multiple versions and you need to change the activation to KMS, it’s important to first create a Merge of the version to a now Base image. This has to be done because you need to change the Microsoft Volume Licensing option within the vDisk properties and dis can only be done on al the versions and only when the vDisk isn’t locked.
Important: you need at least 25 Windows 7 clients or 5 Windows 2008 R2 host using KMS to get it work.
After creating a Merge base, copy the VHD and PVP file and rename them to a appropriate name, in this example the new name is “XenAppKMS”, after renaming import the vDisk into the Provisioning Services Console and add it to a test or maintenance device.
