- Scenario
- Performing an enterprise data migration from a commercial Microsoft 365 cloud environment to a Government Community Cloud (GCC) tenant.
- Observed behavior
- The migration requires detailed planning for identity synchronization, compliance adherence, special licensing, and navigating service limitations for SharePoint and Teams.
Before initiating the migration, ensure you have acquired the necessary Cross Tenant User Data Migration add-on licenses and have thoroughly reviewed the compliance and identity requirements specific to the Government Community Cloud (GCC).
Perform Native Cross-Tenant Migration for Mailboxes and OneDrive
Use Microsoft's official cross-tenant migration tools to move core Exchange and OneDrive data to the GCC tenant.
Migrating to a GCC tenant requires specific licensing and compliance checks. Native Microsoft tools fully support Exchange and OneDrive transitions, but require careful configuration of identity synchronization.
Verify that your commercial tenant possesses the required Cross Tenant User Data Migration add-on licenses for all migrating users in the Microsoft 365 admin center.
Deploy and configure Microsoft Entra Connect to synchronize your users, groups, and contacts from your source Active Directory to the target GCC Entra tenant.
Initiate the cross-tenant migration batches for Exchange Online mailboxes and OneDrive via the Exchange admin center and SharePoint admin center following Microsoft's official cross-tenant guidance.
Engage a Qualified Third-Party Migration Solution
For complex workloads like Microsoft Teams and full SharePoint environments, utilizing a specialized third-party tool is highly recommended.
