Upgrade to Apple Business Manager
If you enrolled in Apple Deployment Programs on or after February 26, 2014, your organization may be able to upgrade from Apple Deployment Programs to Apple Business Manager. How you enrolled determines your ability to upgrade. Upgrading includes moving all mobile device management (MDM) servers, device orders and assignments, and management-level accounts.
After upgrading, your Apple Deployment Programs account names are changed in Apple Business Manager as follows:
Program Agent is called Administrator.
Administrators are called managers.
The accounts used to buy licenses of apps and books from the Volume Purchase Program become Content Managers with the continued ability to buy apps and books.
The accounts used to manage MDM servers become device managers.
