You add media to XenMobile so you can deploy the media to user devices. You can use XenMobile to deploy iBooks that you obtain through the Apple Volume Purchase Program (VPP).
After you configure a VPP account in XenMobile, your purchased and free books appear in Configure > Media. From the Media pages, you configure iBooks for deployment to iOS devices by choosing delivery groups and specifying deployment rules.
The first time that a user receives an iBook and accepts the VPP license, deployed books install on the device. The books appear in the Apple iBook app. You can't disassociate the book license from the user or remove the book from the device. XenMobile installs iBooks as required media. If a user deletes an installed book from their device, the book remains in the iBook app, ready for download.
iBooks obtained through VPP appear on the Configure > Media page.
To configure an iBook for deployment:
