If your business is going through a merger, acquisition, rebranding, or IT restructuring, there's a good chance your Microsoft 365 data needs to move from one tenant to another. This process - known as Microsoft 365 cross-tenant migration - is one of the most complex operations in the M365 ecosystem, and getting it wrong can mean lost emails, broken access, and business disruption.
At Trasoltech, we handle Microsoft 365 cross-tenant migrations end-to-end using Microsoft's native migration framework — no third-party tools, no hidden software costs.

A cross-tenant migration is the process of moving users, mailboxes, and data from one Microsoft 365 tenant to another. Unlike a simple domain change, it involves configuring trust relationships between two separate tenants, coordinating admin access on both sides, and carefully sequencing the migration to avoid downtime.
| Workload | Supported |
|---|---|
| Exchange Online Mailboxes | ✅ Yes |
| OneDrive for Business | ✅ Yes |
| SharePoint Site Collections | ✅ Yes |
| Microsoft Teams Data | ✅ Preview |
| Teams Channel History | ❌ Not supported natively |
| Microsoft 365 Groups | ❌ Not supported natively |
We are transparent about limitations upfront — you will know exactly what moves and what does not before we start.
Microsoft requires a Cross-Tenant User Data Migration add-on license — one per migrated user. It is a one-time fee, not recurring. Without it, migrations will fail. We include license planning in every project scope so there are no surprises.
How Trasoltech Handles Your Migration
Third-party migration tools add cost, introduce additional data handling, and require extra licensing. Microsoft's native cross-tenant migration framework is built directly into Exchange Online — keeping your data within Microsoft's infrastructure throughout the entire process.
Whether you are weeks away from a cutover or still in early planning, the earlier we are involved the smoother the migration. Our team has hands-on experience coordinating cross-tenant migrations across both source and target tenants simultaneously.
