Intro to MDM servers in Apple Business Essentials
Devices added to an organisation at the time of purchase or through Apple Configurator can be assigned to a mobile device management (MDM) solution (called an MDM Server in Apple School Manager), and organisations can have multiple MDM servers.
Assigning a device to an MDM server is a setting that is applied the next time a device or devices go through Setup Assistant. Those devices use Automated Device Enrolment, allowing the device to be enrolled into management during initial setup. Assigning an MDM server does not affect a current enrolment of a device.
