Apple VPP Licensing
The Apple Volume Purchase Program (VPP) supports two types of licensing: Redemption Codes and Managed Distribution. These license types are not interchangeable.
Redemption Codes
Redemption codes are single-use licenses. Each code can only be redeemed once and is permanently linked to the Apple ID associated with the target device at the time of assignment. If the device is unenrolled from SOTI MobiControl, the application is removed but the license remains linked to the device and the code cannot be unredeemed.
Redemption codes are supported on devices running iOS 6 or later.
Managed Distribution
Managed distribution tokens are reusable and can be revoked and reassigned to different devices. SOTI MobiControl communicates with Apple VPP servers for the management and inventory of VPP managed distribution licenses.
To use managed distribution licenses, you must link your VPP account to SOTI MobiControl.
Managed distribution licenses can be assigned to either an Apple ID or to the device itself. If necessary, you can convert between assignment types. With both assignment types, when a device is unenrolled from SOTI MobiControl, VPP apps are automatically removed and their licenses become available again.
User based assigns licenses to the Apple ID on a device. It is the default assignment type and available with all applications.
Device based assigns licenses directly to the device rather than to the Apple ID on the device. It is recommended for devices that you expect to have multiple owners over their lifetimes. It is only available on devices running iOS 9 or later and some applications may not support device based assignment.
