At the Worldwide Developers Conference 2025, Apple introduced a new feature that solves one of the biggest pain points for IT administrators: migrating iOS/iPadOS and macOS devices from one mobile device management (MDM) solution to another — without resetting to factory settings, no manual re-registration, and no lost configurations.

With the new MDM migration, which is integrated directly into Apple Business/School Manager (ABM/ASM) starting with macOS 26 and iOS/iPadOS 26, devices can be seamlessly transferred from third-party MDMs to Relution – without any interruption for users.

For interested parties, this means:

• Easy switch to Relution without downtime
• No manual processes on the end device
• Reduced administrative effort

In this article, you will learn how to use the new Apple feature with Relution to migrate your device fleet to Relution securely and efficiently.

1. Before migration – preparation and setup

1.1 Check requirements

Check the current MDM inventory to ensure that all devices have the necessary operating system (iOS/iPadOS 26/macOS 26). Devices that are not yet running the current operating version must be updated via the existing MDM. This ensures that only compatible devices are migrated.

1.2 Document existing configurations

Make a note of all settings in your current MDM system, e.g.:

• Device information: (name, group membership)
• Configuration profiles (Wi-Fi, VPN, email, certificates)
• Compliance policies (password rules, encryption)
• Security standards (FileVault, Gatekeeper, firewall)
• Scripts (automation, monitoring)
• Apps & distribution channels (App Store, VPP, custom apps)

This documentation is your template for rebuilding in Relution.

1.3 Connecting Relution with Apple Business/School Manager

• Connecting DEP tokens from ASM/ABM with Relution
• Connect VPP token from ASM/ABM to Relution

1.4 Prepare policies in Relution

Based on your documentation, you should:

• Create new network policies
• Map security and compliance requirements
• Reassign apps
• Apply automation scripts

Tip: Test the configurations on pilot devices first before migrating the entire fleet.

2. Migration – Admin workflow

The migration starts in Apple Business / School Manager:

• Select devices and click “Assign device management”

• Select Relution as MDM

• Set migration deadline

• Confirm assignment

3. Migration – End device workflow

After assignment, users receive a notification that a management change is required. The migration can now be started immediately or postponed. If the deadline set by the administrator is exceeded, a full-screen prompt appears, which must be completed before further use.

The devices automatically install the new MDM profile from Relution—without resetting the device to factory settings.

4. After migration—checking and fine-tuning

Check in the Relution portal whether all devices have been transferred correctly. Test security-related configurations and functions before rolling out the migration on a large scale.
