Release devices in Apple School Manager
Devices can be removed from Apple School Manager. You remove a device from the programme if it has been sold or lost, or cannot be repaired. This is called releasing a device. Under the terms and conditions of Apple School Manager, you are legally required to release any devices you no longer own.
You can also allow your mobile device management (MDM) solution to release devices. This method does not require you to sign in to Apple School Manager. This feature is enabled by default when you add an MDM server. You can remove this feature by unchecking the box Allow this MDM Server to release devices for any new or existing MDM servers you created.
Important: If an iPhone, iPad, iPod touch, or Apple TV is removed from Apple School Manager, it can be added back using Apple Configurator 2.5 or later. Mac computers cannot be added back using Apple Configurator 2.5 or later. iPhone, iPad, iPod touch, Apple TV and Mac computers can be added back by participating Apple Authorised Resellers or carriers. Do not release devices that are being sent to Apple for repair. If Apple replaces a released device as part of a repair, its replacement will not be available in Apple School Manager.
In Apple School Manager , tap Device Assignments in the sidebar and choose the method for device release:
If you choose Serial Number: enter each serial number separated by a comma.
If you choose Order Number: the quantity and type of devices are shown.
If you choose Upload CSV File: You also upload a comma-separated value (.csv) file that contains a list of device serial numbers.
Choose Release Devices from the Perform Action pop-up menu, then tap Done.
Carefully read the 'Are you sure you want to release this device?' dialogue, tap Release, then tap OK.
Verify that the devices have been removed by searching for the serial numbers in the search field at the top of the window.
