A tenant to tenant migration in Microsoft 365 involves moving users, mailboxes, OneDrive data, Teams, SharePoint, and other services from one Microsoft 365 tenant to another. This type of migration typically occurs during mergers, acquisitions, or organizational restructuring. While the process may seem straightforward, it requires careful planning and execution to avoid data loss, downtime, or disruption to users.

Key components of tenant to tenant migration include domain verification, user mapping, data transfer, and reconfiguration of security and compliance settings. Mailbox migrations are usually handled via Exchange Online PowerShell or third-party tools, while Teams and SharePoint content require specialized handling to maintain structure, permissions, and links.

Timing is critical—especially in large organizations—as the process often needs to be performed outside of business hours to minimize impact. Thorough communication with users and testing before the full cutover are essential to ensure a smooth transition.
