Introduction
To simplify cross-tenant migrations, we’re introducing a unified interface that enables administrators to move user data—including Exchange mailboxes, OneDrive files, and Teams chats and meetings—across Microsoft 365 tenants. This streamlines migration workflows and supports seamless collaboration during organizational transitions.
When this will happen
Public Preview (Worldwide): Begins early December 2025.
