How to Merge Two Office 365 Tenants After a Company Acquisition?

When organizations merge or acquire another company, consolidating two Microsoft 365 tenants is often necessary to unify users, data, and collaboration resources. The Aryson Tenant to Tenant Migration Tool helps IT administrators migrate data between Microsoft 365 tenants while maintaining the original folder structure and metadata. It supports modern Microsoft authentication and enables administrators to migrate multiple user accounts in a single operation.

The tool can transfer Exchange Online mailboxes, OneDrive accounts, SharePoint Online sites, Groups, and other Microsoft 365 workloads from the source tenant to the destination tenant. It provides filtering options for selective migration, supports incremental migration to avoid duplicate data, and generates detailed reports that help administrators monitor the migration process. This makes it suitable for tenant consolidation projects resulting from mergers, acquisitions, restructuring, or organizational changes.
