Assign a device that was serviced or replaced in Apple School Manager
Service a device
You should unassign the following devices from the mobile device management (MDM) server in Apple School Manager before the device is subject to AppleCare service:
iPhone
iPad
Apple TV
Note: Mac computers don’t have to be unassigned.
When the device is returned, you can reassign it to the same MDM server.
Replace a device
If you replace an iPhone, iPad, or Mac currently enrolled in Apple School Manager through an Apple Authorized Service Provider, the replacement device is usually also available for enrollment. You can manually assign the device to a server using your order number. To find replacement devices, search for order numbers that begin with the letter R.
Important: Before you send in or bring in an iPhone, iPad, or Apple TV to be repaired, unassign it from your MDM server in Apple School Manager. If you don’t, it might be returned to you without being repaired. If your Mac is enrolled in Apple School Manager, it stays enrolled when you get it repaired.
