Can Microsoft 365 data be migrated between tenants?

Yes. Microsoft 365 data can be migrated from one tenant to another, which is commonly required during mergers, acquisitions, company restructuring, domain changes, or tenant consolidation.

Using the Aryson Tenant to Tenant Migration Tool, administrators can migrate multiple Microsoft 365 workloads between source and destination tenants, including:

Exchange Online mailboxes – emails, folders, attachments, and mailbox data
OneDrive – user files and folder structures
SharePoint Online – sites, documents, lists, and associated permissions
Microsoft Teams – supported Teams data and collaboration content
Folder hierarchy and metadata – helping maintain the original organization of migrated data
Permissions and sharing settings – where supported by the selected migration workload

The tool also supports bulk user mapping, CSV-based mapping, selective migration, incremental migration, batch processing, scheduling, and detailed migration reports, making it suitable for organizations migrating many Microsoft 365 users.

How it works
Connect the source Microsoft 365 tenant and authorize the required permissions.
Connect the destination tenant with the appropriate administrative permissions.
Map source users to destination users, manually or through CSV.
Select the workloads you want to migrate, such as Mailbox, OneDrive, SharePoint, and Teams.
Apply filters or migration options if you want to migrate only specific data.
Start the migration and monitor progress through the tool’s logs and reports.

So, rather than migrating only Exchange mailboxes, Aryson Tenant to Tenant Migration Tool provides a centralized approach for moving Microsoft 365 mailbox, OneDrive, SharePoint, and Teams data between tenants.

Yes, Microsoft 365 data can be migrated from one tenant to another. For mailbox migration, the source and destination tenants need to be configured properly, including user accounts, permissions, authentication and mailbox mapping.

If you have several mailboxes to move, the WholeClear Office 365 to Office 365 Migration Tool can simplify the work by transferring emails, attachments, contacts, calendars, and other mailbox data between tenants. Instead of handling each mailbox separately, you can select the required accounts and migrate their data to the corresponding users in the new tenant. Additionally, the software can smoothly work on macOS, Linux and Windows, making it a smart solution for different operating systems.

Before starting, I’d verify the admin permissions, source and destination accounts, and user mapping. For a large cross tenant migration, testing one mailbox first is also a good way to catch configuration issues before moving the rest.

Yes, Microsoft 365 data can be migrated between two different tenants, but the process depends on what you need to move—mailboxes, OneDrive, SharePoint, Teams, or other data. A tenant-to-tenant migration usually requires proper preparation, including user mapping, domain/DNS planning, permissions, and migration of mailbox data. For larger environments, an automated migration tool can simplify the process and reduce manual effort. For example, SysTools Office 365 Express Migrator can help migrate Microsoft 365 mailboxes and other supported data between tenants while preserving the original folder structure and email content.
