Prepare the Source Environment
- Create a OneDrive for Business user account that will be used for the migration, and give it main global administrator privileges or use the existing global administrator account that was set up at the time the Office 365 tenant was created. KB004948
Note: We highly recommend that you use an administrator account that isn’t one of the users being migrated. Otherwise, it can cause issues with missing shared permissions.
- 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 users into your MigrationWiz project dashboard. KB004519
Prepare the Destination Environment (Google Drive)
- Grant MigrationWiz OAuth2.0 access to authenticate to Google Drive. KB005019
G Suite as the Destination (full scopes):
https://mail.google.com/, https://www.google.com/m8/feeds, https://www.googleapis.com/auth/contacts.readonly, https://www.googleapis.com/auth/calendar.readonly, https://www.googleapis.com/auth/admin.directory.group.readonly, https://www.googleapis.com/auth/admin.directory.user.readonly, https://www.googleapis.com/auth/drive, https://sites.google.com/feeds/
- Add users to Google Drive. The instructions are located here.
- Create the customer. KB005421
- Create the OneDrive for Business and G Suite endpoints.
- Click on EndPoints > Add Endpoint > Enter endpoint name > For endpoint type, select OneDrive for Business. Enter the global admin account and password in the appropriate fields.
- When entering the admin credentials at the Source, it is easiest to use the vanity domain name, rather than the .onmicrosoft.com domain name. This way the domain name will match the domain name of the users.
- Alternatively, if you are determined to use admin credentials with the .onmicrosoft.com domain name, you must change the usernames to also use the .onmicrosoft.com domain name. These can be set in the CSV file (created under Step 2 of the "Prepare the Source Environment" section of this guide) before importing, or afterwards via PowerShell. An example script for this is provided in KB005117.
- We recommend that you confirm that the admin account and the users have matching domain names (whether .onmicrosoft.com or the vanity domain). This will ensure that permissions are correctly migrated.
For the Destination endpoint:
- Create the Document Migration project. KB005070
Add the accounts (also referred to as "items") that will be migrated to the project. KB004842
Set Project Advanced Options. KB004834
- Create the Document Migration project > Select the customer > Select the Source endpoint (OneDrive for Business) > Select the Destination endpoint (Google Drive).
Run Verify Credentials. KB004511
Purchase Document Migration licenses. KB004647
Notify users that a migration is occurring. Send email to all users telling them the time and date of the migration. During this time, they should not modify any documents in their OneDrive for Business accounts, because any modifications will not be included in the migration.
Perform the migration using one of the following strategies:
Click on the pie chart icon in the MigrationWiz dashboard to receive an email containing all the project migration statistics. KB004626
- Set the value for maximum licenses to consume per item, per pass. The default value is one license per user, which allows up to 10GB to be migrated per user. However, if a user has 28GB of data, the migration will pause at 10GB, and you will have to assign more licenses to the user. The recommended maximum licenses to consume per user for a document migration project is five (5) licenses per user, which allows up to 50GB of data to be migrated per user. The project will only consume the number of licenses for the amount of data migrated. If a user has 28GB of data, then only three out of the five licenses will be consumed, and two licenses will remain. KB004890
- Under Support/Support Options add:
- InitializationTimeout=28800000 - This increases the initialization timeout window to eight hours. KB005099
- FolderLimit=20000 - This increases the maximum number of folders for the migration to 20,000. Large companies might have more than 10,000 folders (the default) to migrate, so we recommend increasing the folder limit to 20,000. KB005557

To prevent users from inadvertently logging in and using their OneDrive for Business accounts, decommission the OneDrive for Business user accounts, or change their passwords.
