In migrating accounts using GWMME, how should user entries be organized in the control CSV file?

When migrating accounts using Google Workspace Migration for Microsoft Exchange (GWMME), it is essential to organize user entries correctly in the control CSV file to ensure a smooth migration process. The control CSV file should list old and new email addresses. This is crucial because GWMME needs to map the users from their existing email addresses in the source system (like Microsoft Exchange) to their new Google Workspace email addresses.

By clearly specifying both the old and new email addresses, GWMME can accurately transfer the emails, contacts, and other relevant data from the legacy system to the new Google Workspace environment. Correctly mapping these addresses prevents any loss of data during the migration, helps maintain user continuity, and ensures that users can seamlessly access their information once the migration is complete.

The other options would not provide the necessary information for the migration. For instance, organizing entries with just usernames would be insufficient as it would not clarify where to migrate the email data from and to. Alphabetical organization based on last names would not ensure the necessary data paths for migration. Additionally, including additional user metadata is generally not required for the basic migration process and may complicate the CSV file format beyond what GWMME needs to function effectively.
