Your migration failed checking destination credentials. Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application. You must call the Connect-MsolService cmdlet before calling any other cmdlets.
This error occurs in Document migrations with OneDrive for Business as the destination and Multi-Factor Authentication or ADFS is enabled on the destination.
Multi-Factor Authentication or ADFS will need to be disabled or an administrator account that has been set up without the extra authentication requirements can be used.
For more information see Will MigrationWiz work when two-factor or multi-factor authentication is in place?
