Hi, Insiders! I am Rebecca Wood, a Product Manager on the Enterprise and Cloud team. I’m excited to tell you about cross-tenant orchestrated user data migration in Microsoft 365, our new product for moving user data and workloads between separate Microsoft 365 tenants.

Simplify cross-tenant user migrations with Microsoft 365 orchestrator

The orchestrator, also known as cross-tenant orchestrated user data migration, is a self-service product for customers undergoing mergers, acquisitions, and divestitures.

It was made for customers who wanted to use an in-house Microsoft solution that keeps all Microsoft 365 data within the Microsoft boundary. For the first time, we’re offering a product that moves Teams Chats! In addition, we have built an improved experience for migrating Teams Meetings.

How it works

Orchestrator is an opt-in feature that runs through PowerShell, where tenant admins can batch and schedule the migration of a user's mailbox, OneDrive, Teams meetings, and Teams chats.
