Question details

The user needs to migrate files from a commercial Microsoft 365 SharePoint environment to a GCC High tenant while understanding the limitations regarding metadata preservation.

How to Transfer Files from Commercial SharePoint to GCC High

Product: Microsoft SharePoint
Device & OS: not provided
Scenario: Migrating data between different Microsoft 365 cloud environments, specifically moving from a commercial tenant to a Government Community Cloud (GCC) High tenant.
Observed behavior: Basic manual migration methods may result in the loss of metadata, permissions, version history, and other built-in SharePoint properties.

Before you start

Ensure you have administrative access to both the commercial and GCC High SharePoint environments, and verify that your local computer has sufficient storage capacity to handle the file synchronization process.

Solution 1Recommended

Synchronize Files via Local OneDrive Client

Use the OneDrive sync client to download files from the commercial tenant locally and manually copy them to the GCC High tenant.

Because there is no built-in direct migration tool for moving files from a commercial tenant to a GCC High tenant, you can use your local computer as a bridge. This manual process relies on the OneDrive sync client to handle the download and upload processes.

Sync the Commercial SharePoint Library

Open your commercial SharePoint document library in a web browser. Click the **Sync** button located on the top command bar to synchronize the library to your local computer.

Add GCC High Account to OneDrive

Right-click the OneDrive cloud icon in your system tray, select **Settings** (gear icon), navigate to the **Account** tab, and click **Add an account**. Sign in using your GCC High credentials.

Sync the Target GCC High Library

Log into your GCC High SharePoint environment in the browser, navigate to the destination document library, and click the **Sync** button to create a local folder connected to the new tenant.

Copy and Paste the Files

Open File Explorer. Select and copy the files from the commercial SharePoint synced folder, then paste them into the newly created GCC High synced folder. OneDrive will automatically upload the files to the GCC High tenant.

Metadata and Permissions Limitation: This manual copy-and-paste method will not retain metadata (like 'Created By' or 'Modified By'), custom permissions, or version history. For comprehensive migrations, consult your Microsoft 365 administrator or open a Microsoft support request for specialized migration tool guidance.

Frequently Asked Questions

Can I preserve file version history when moving to GCC High using local sync?

No, using the manual local synchronization method will only copy the latest version of the file. To preserve complete version history, you typically need to use specialized third-party migration tools or seek Microsoft-assisted migration services.

Are file permissions retained during a manual tenant-to-tenant transfer?

No. When you copy files locally and upload them to a new tenant, the original SharePoint permissions and sharing links are lost. You will need to reconfigure sharing and permissions manually in the new GCC High tenant.

What is a GCC High tenant in Microsoft 365?

GCC High (Government Community Cloud High) is a specialized, highly secure Microsoft 365 cloud environment designed specifically to meet the stringent cybersecurity and compliance requirements of US government agencies and defense contractors.
