OneDrive GCC High/China to OneDrive for Business Migration Guide

This guide is for migrations from OneDrive GCC High/China to OneDrive for Business. The source must be OneDrive GCC High/China and the destination must be OneDrive for Business - not the personal OneDrive version. GCC High/China OneDrive migrations do not utilize Azure Storage for the destination endpoint.

Due to limitations on connections allowed by GoDaddy, we do not support migrating to or from GoDaddy using this migration type.

OneDrive Migrations

Note that OneDrive data may not be accessible for a few days after migration, due to OneDrive's crawling and indexing process. We suggest you have your users log in immediately after migration but let them know that their data may not be available for a short period. For this reason, it may be best to complete the migration on a Friday so the indexing can happen over the weekend.

This endpoint does not support the User's personal site provisioning. The AO DestPersonalSiteIsProvisioned=1 must be used. Refer to Advanced Option.

Due to versioning forced by the destination, storage usage in OneDrive may be increased when migrating with permissions.

First migration?

We have created a guide on scoping, planning, and managing the migration process. If this is your first migration, we recommend reading this guide carefully.


MigrationWiz is a migration tool, not a syncing tool. If changes are made at the source after migration, they will not sync to the destination, nor will changes made at the destination sync to the source. We do not have “live” monitoring of changes (as with a sync agent) and cannot handle scenarios such as conflict resolution without user interaction.

MigrationWiz supports the capability to share migration projects across a Workgroup. When the Project Sharing feature is turned on, all Agents besides those who are Inactive can view all migrations projects. 

We are not able to support migrations with two-factor or multifactor authentication. 

Migration of Versions and Metadata is not supported for GCC High/China as a source or destination

Preparing the Source

Steps for Enabling Delegated App Permissions

GCC High endpoints require using delegated permissions. The easiest approach is to use the global administrator account set up at the time of tenant creation. However, if you do not wish to use this global admin account during migration, you can create a new user account instead. This new account will then need a license assigned, including a OneDrive for Business, and be granted either Global Administrator permissions or SharePoint Administrator privileges.


We strongly recommend you use an administrator account that is not being migrated to avoid missing shared permissions.


  1. Create a user in Microsoft 365 and assign a license that includes OneDrive for Business. For step-by-step instructions, see the Microsoft article Add users and assign licenses at the same time.
  2. Grant the new user Global Administrator permissions or SharePoint Administrator rights in Microsoft 365.
  3. Grant Site Collection Administrator privileges to the user OneDrives in the source being migrated in the project. 
  4. Ensure the administrator account is not set to use MFA, 2FA, or app password.
  5. Go to MigrationWiz-SharePoint-Delegated for GCC High tenants (This will install the app via login at and consent to the app access when prompted. Once you click on Accept, you will be redirected to the BitTitan login page. This is normal and the page can be closed.
  6. Add the support option UseApplicationPermissionAtSource=0 to the advanced options of the MigrationWiz project under Support Options.

After you perform these steps, the specified user will be visible in the Microsoft 365 administrator center. Full provisioning of the user account can take up to 24 hours.

Prepare the Destination Environment

BitTitan uses app-based authentication for commercial SharePoint, OneDrive for Business, Microsoft 365 Groups (Documents), and Teams endpoints. This provides greater security and reduces the potential of Microsoft throttling. It replaces the previous Microsoft 365 authentication, which has been subject to increased throttling by Microsoft. This app-based authentication method is specific for Microsoft 365 tenants. Using this option, including steps for uninstalling, can be found outlined here: App based authentication using Application Permissions for SharePoint and OneDrive Migrations

Steps for Enabling App-based Authentication Permissions

  1. Ensure you are signed in as a Global Admin.
  2. Go to MigrationWiz-SharePoint-FullControl and consent to the app access when prompted. Once you click on Accept, you will be redirected to the BitTitan login page. This is normal and the page can be closed.

  3. Create a new security group named MigrationWiz in the Office 365 Admin Portal. (The name of the security group must be an exact match)

  4. Create a new user that is not having data migrated in the project. This account does not require any administrator roles to be assigned. (If you already have an existing user, that should be fine) This user must have a SharePoint/OneDrive license applied.

  5. Add the new (or existing) user to the previously created security group as a Member (Adding as an Owner will not work here).

  6. Create MigrationWiz project.

  7. When creating the source and destination endpoints, enter the user credentials of step 4 that correspond to the endpoint the user belongs to.

  8. Add the support option UseApplicationPermissionAtDestination=1 to the advanced options of the MigrationWiz project under Support Options.

Export Users

Export the list of OneDrive for Business user accounts to a CSV file. This can be used when adding users on the Destination, and when adding the users to the project in MigrationWiz. 

MSPComplete Steps

  5. Enter a Billing address if applicable.
  6. Click Next.
  7. Review the Order Summary and enter a payment method.
  8. Click Place Your Order.

Apply for Licenses

  1. Select the correct workgroup on the top of the left navigation pane. This is the workgroup that the customer and migration project were created under. Your account must be part of the workgroup if the project was not created under your account.
  2. On the left navigation pane, click Customers.
  3. Click the customer that employs the user to whom you want to apply for a User Migration Bundle license.
  4. Click the Users tab at the top of the page.
  5. Check the box to the left of the email for the user(s) to whom you want to apply for a license.

Then apply User Migration Bundle Licenses, before editing to show the .onmicrosoft domain, if the .onmicrosoft domain will be used for the migration.
  7. If there is at least one unassigned User Migration Bundle license available for each selected user, click Confirm.

MigrationWiz Steps

Create a Document Project

  1. Log in to MigrationWiz.
  2. Click the Go to My Projects button.
  3. Click the Create Project button.
  4. Select the Document project type. 
  5. Click Next Step.
  6. Enter a Project name and select a Customer.
  7. Click Next Step.


Endpoints are now created through MigrationWiz, rather than through MSPComplete. The steps for this section outline how to create the endpoints in MigrationWiz.

Consider only ten endpoints will be shown when selecting an existing endpoint. If you have more than ten, you may need to search. Endpoint search is case and character-specific. For example, Cust0mer will not show up if the search is customer. We recommend keeping a list of endpoints you have created with any unique spellings or capitalization you may have used.

You may either use existing endpoints or create new ones. 

Create a Source Endpoint

  1. Click Endpoints.
  2. Click New.
  3. Select the OneDrive for Business endpoint type. 
  4. Leave the Provide Credentials option selected.
  5. Click Add Endpoint

Create a Destination Endpoint

  1. Click Endpoints.
  2. Click New.
  3. Select the OneDrive for Business endpoint type. 
  4. Choose the OneDrive for Business (GCC or China migrations) migration type.

  5. Enter the administrator username and password in the proper fields. 
  6. Click Add Endpoint.

Add Users

Add the user accounts that will be migrated to the project. MigrationWiz allows you to bulk import users into the system.

You may use Bulk Add, Quick Add, or add the accounts to the MSPComplete customer. 

Quick Add
This option allows you to add items one at a time. To do so, you only have to provide an email address if you entered administrative credentials when setting up the project. If you did not, enter the following user information:
  • An email address
  • Login name
  • Password
  • Mailbox status
Bulk Add

Bulk Add uses a CSV containing the source and destination email addresses for the users to add the users to the project. If migrating only a specific group from a tenant, we recommend using the Bulk Add option.

MigrationWiz allows you to bulk import mailboxes into the system.

To import one or more mailboxes:

  1. Sign in to your MigrationWiz account.
  2. Select the Project for which you want to perform the bulk import.
  3. Click Add.
  4. Click Bulk Add.
  5. Follow the instructions on the page.

Run Verify Credentials

  1. ​Sign in to your MigrationWiz account​
  2. Open the Project containing items you wish to validate.
  3. Select the items you wish to validate.
  4. Click the Start button in your dashboard.
  5. Select Verify Credentials from the drop-down list.

Once complete, you can review the verification results in the Status section.​ 

To lock (set to ReadOnly) the OneDrive items before migration: 

  1. Make sure all OneDrive line items are not locked.

  2. Run Verify Credentials pass for all OneDrive line items. This will add the provided credentials as a site collection administrator for these items.

  3. You can now lock all the OneDrive line items.

  4. Run a full migration pass.

Notify Users

Notify users that a migration is occurring. Send an email to all users telling them the time and date of the migration.

Advanced Options

The following advanced options show you some options that will help you to perform or complete a migration.

Support Tab

Consider that each Support Option includes the "=" character and is to be entered under the Support tab in the section named Support Options.

Add additional blank fields for new Support Options by clicking the "+" button. In case you want to delete a field click the trash can icon.


Add the following options in the Advanced Options and Support Options tabs (if needed). 

  • For non-standard URL endpoints, add OneDriveProExportAdminUrl=<non standard URL> and OneDriveProImportAdminUrl=<non standard URL>. (Replace "<non standard URL>" with your custom URL.) 
  • InitializationTimeout=8 - This increases the initialization timeout window to eight hours. This is especially useful for large migrations.
  • IncreasePathLengthLimit=1 - Use this Advanced Option in MigrationWiz to enable the use of 400 characters for the file path name. OneDrive limits characters in file path names, which can cause errors when migrating folder structures.
    • BitTitan has no limitations to the number of folders per migration. Microsoft sets any folder limits.
    • There are no spaces on either side of the "=" sign, and the entries are case-sensitive, so pay special attention to the capital letters in the commands above.
  • If migrating from a GCC High US Government Tenant, add:

  • If migrating from a China Tenant, add:

  • DestPersonalSiteIsProvisioned=1
    • For OneDrive users to specify a destination personal site has already been provisioned so MigrationWiz will use App-based authentication for OneDrive personal site retrieval instead of basic authentication.
  • MapPermissionEmailByPairsInProject=1
    • Use this advanced option only for OneDrive/Google Drive at the destination in scenarios where usernames change during a migration, you will need to run the following command to ensure permissions map to the new username. For example to


      Permissions generally cannot be migrated unless the prefix of the mail address is the same in the source and the destination. However, choosing Support Option MapPermissionEmailByPairsInProject=1 will allow permissions to be migrated without identical mail addresses.

Notifications Tab

Set the Advanced Option to send a notification to end users after the migration pass completes. (This is optional.) To set up the notification:

  1. Click Notifications.
  2. Click Send successful migration and notification to:
  3. Select the Source email address (if users are still using the source Microsoft 365 tenant) or the Destination email address (if users are already using the Destination Microsoft 365 tenant).

Customize notification email:

  1. Checkmark the Customize "successful migration" email option.
  2. Add your own customization text and company name to this email.
  3. Notifications should only be set up before the final pass. Please consider the following cases to set up this setting:
    • Set this up now if performing a single, Full pass.
    • Only set this up before the final Full (Delta) pass when following a Pre-Stage migration strategy.

If the migration project is a long-term project, an Advanced Option may be necessary during the final migration pass to verify previously migrated items. For more information, contact Support.

Filtering Tab

Excluding OneNote Files

Please be aware that OneNote does not support versioning. To avoid creating duplicate content, it is crucial to migrate your OneNote files just once. Each subsequent migration attempt could result in new versions of your OneNote files being generated as separate new files.

To prevent this, we advise filtering out OneNote files during various stages of the migration process by adding one in the Advanced Options. Consider excluding OneNote files during the Trial Migration and Pre-Stage Migration. 


We recommend only including them in the final Full Migration stage to ensure a smooth and efficient migration process. To ensure the successful migration of OneNote folders and files, particularly after initially excluding them, it is necessary to remove the one extension from the filtering tab in the Advanced Options.

Run Migration

We suggest skipping the pre-stage pass and only performing the full migration for small migrations. However, we recommend performing the pre-stage migration for large migrations with more than fifty users.

Recent changes to the Dropbox APIs prevent us from adding watermarks on files in the Destination Dropbox accounts. Therefore, if you perform a partial migration, reset the items in MigrationWiz, and then perform the migration again, you will end up with duplicate files at the Destination. If you must rerun the migration, first delete all files already migrated to the Destination Dropbox accounts.

Pre-Stage Pass

  1. Select the users to migrate.
  2. Click the Start button from the top.
  3. Select Pre-Stage Migration.
  4. Under the Migration Scheduling section, from the drop-down list, select 90 days ago.
  5. Click Start Migration.

Full pass

  1. Select the users.
  2. Click the Start button from the top.
  3. Select Full Migration.
  4. Click Start Migration.

Run Retry Errors

Look through the user list and click any red "failed migration" errors. Review the information and act accordingly.

If problems persist contact Support.
