I'm are attempting to use the device management migration feature in Apple Business Manager / Apple School Manager (for devices running iOS 26 / iPadOS 26) to re-assign managed devices from one MDM server to another. We followed the published procedure (select device(s) → Assign Device Management → Set deadline → Continue).
However, we are observing that on the device side, no notification or prompt appears to the user (such as “Enrollment Required” or “Your organization requires this device to enroll in a different device management service”), even after the migration deadline has passed.
Here are the environment details:
- Device OS version: (iOS 26.1)
- Device ownership: enrolled via
Automated Device Enrollment
- MDM re-assignment in ABM: old MDM server（name: https://dev5.clomo.com/panel/mackey-dev/ ） → new MDM server (name: https://obliging-bunny-equally.ngrok-free.app/ )
- Deadline set: (12/10/2025 12:00 AM)
- Network connectivity: confirmed online at deadline time
We would like to know:
- Under what exact conditions will the device display the notification/prompt, and what common mis-configurations prevent it from appearing?
- Is there any device log or activity indicator in ABM/ASM to confirm that the migration instruction has been sent to the device?
- In cases where the prompt does not appear, what troubleshooting steps can we perform on the device (or in the MDM/ABM configuration) to correct it?
