Public Preview: Cross-tenant Orchestrated User Data Migration

Confidently migrate user data across tenants. Automate cutover, keep teams connected, and stay secure.

What’s new Today we’re excited to announce the Public Preview of Cross-tenant Orchestrated User Data Migration (UDM), a new set of capabilities that help IT teams move user mailboxes, files, and collaboration assets between Microsoft 365 tenants with greater speed, predictability, and control.

Whether you’re consolidating after a merger, divesting a business unit, or reorganizing globally, this Public Preview brings a guided, endtoend migration experience that reduces manual steps and helps keep users productive during the transition.

Migrate more data in a single product With a single orchestration layer coordinating the migration of multiple services, admins won’t need to manage timelines, dependencies, or interfaces of multiple tools. The submission and monitoring of a migration is all available in one spot, and batching of up to 2,000 users is supported.

All data stays within the Microsoft boundary – so migration is fast and secure.
