It is now time to add which users you would like to migrate.
When migrating from Office 365, you will be able to get users by selecting the down arrow on Add items to migrate and then selecting Get items from source. If this option is unavailable, you can manually import users via a CSV file or simply add them individually via the Add User button.
At this point you can choose what to migrate for each user, when migrating from Office 365 you can migrate mail, contacts, calendars, tasks, files, and sites.
Enter your user's full email address within the Export Name field. If you have already created your Office 365 users, then you will just need to enter their username.
To migrate files to a G Suite Team Drive, either select the item you wish to migrate and select 'Migrate as Team Drive' from the actions menu or specify the import type as 'TeamDrive' when adding an item. You can then specify the name or ID of the Team Drive in the 'Given Name' field. If the Team Drive specified doesn't exist, then it will be created. You can use a unique ID in the 'Import Name' field to identify the Team Drive across multiple migrations. Finally, you must make sure your migrating account has organizer permissions for any Team Drives that are being migrated.
