Microsoft 365 tenant-to-tenant migration is often required during mergers, acquisitions, company restructuring, or tenant consolidation. It allows organizations to transfer users, mailboxes, SharePoint data, and licenses between Office 365 tenants.
If your organization uses an Enterprise Agreement, Microsoft Support can help you remap and transfer Office 365 licenses between tenants.
There are two main ways to perform a Microsoft 365 tenant-to-tenant migration:
- Using Microsoft’s native tools
- Using third-party migration tools
The best choice depends on your organization’s size, complexity, and available technical expertise.
Cross Tenant Migration Options
If you are not signed up for Microsoft Enterprise Agreement then another option is to use a third-party migration tool. These tools can make the migration process much faster and easier, and they often offer additional features, such as the ability to migrate data from other cloud platforms.
The best way to perform an Office 365 tenant to tenant migration will depend on the specific needs of your organization. If you are unsure which method is right for you, it is a good idea to consult with a Microsoft partner or a third-party migration specialist.
