Release devices in Apple Business Manager
Devices can be removed from Apple Business Manager. You remove a device from the programme if it has been sold, lost or cannot be repaired. This is called releasing a device. Under the terms and conditions of Apple Business 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 Business 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 Business 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 Business Manager.
In Apple Business Manager , sign in with an account that has the role of Administrator or Device Manager.

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 click Done.
Carefully read the 'Are you sure you want to release this device?' dialogue, click Release, then click OK.
Verify that the devices have been removed by searching for the serial numbers in the search field at the top of the window.
Note: After a device is released, it must be erased and restored.
