For Tenant-to-Tenant migration, which involves transferring data between two Microsoft 365 tenants (e.g., from one organization’s Microsoft 365 to another), you can use the following tools:

1. Microsoft 365 Migration Tool (Native)

• Microsoft 365 Tenant-to-Tenant Migration Tool: Microsoft provides some native tools for migrating mailboxes, data, and user accounts between tenants, though these are more limited in scope and complexity. You can use PowerShell scripts to migrate user mailboxes, shared mailboxes, and groups across tenants, but this requires technical expertise.

2. Third-Party Tools

Several third-party tools simplify the Tenant-to-Tenant migration process, handling more complex scenarios like SharePoint, OneDrive, Teams, and more.
