: 2 Explanation: The Transfer Appliance is a high-capacity storage device that allows you to transfer and ship your data to a Google upload facility in a safe manner. Once your data arrives at the facility, we upload it to Cloud Storage on your behalf. Getting the appropriate individuals on board, getting an early start on the planning process, and testing your transfer plan before putting it into action in a live scenario are all stages that are required in the process of migrating large datasets.
