Create an Administrator Account
The easiest approach to follow is to use the global administrator account that was set up at the time of tenant creation. However, if you do not wish to use this global admin account during migration, then a new user account can be created instead. This new account will then need to have a license assigned that includes OneDrive for Business and be granted either Global Administrator permissions or SharePoint Administrator privileges.
Important: We strongly recommend that you use an administrator account that isn’t one of the users being migrated, as it can cause issues with missing shared permissions.
- Create a user in Office 365 and assign a license that includes OneDrive for Business. For step by step instructions, see the Microsoft article Add users individually or in bulk to Office 365.
- Grant the new user Global Administrator permissions or SharePoint Administrator rights in Office 365.
- Ensure that the administrator account is set to use Basic authentication rather than Multi-Factor authentication.
After you perform these steps, the specified user will be visible in the Office 365 administrator center. Full provisioning of the user account can take up to 24 hours.
