Migrating to a new G Suite account can be an exciting but overwhelming experience, especially when dealing with years of accumulated data from old accounts. To avoid losing important emails, contacts, and calendars, it's essential to back up data from old accounts before importing them into the new G Suite account. Google provides various tools and services to facilitate this process, including the ability to copy over emails from almost any email account and bulk import entire teams' email, contacts, and calendars from Microsoft Exchange servers. Additionally, Google Takeout allows users to export nearly all their data from Google accounts, while Zapier's automated workflows can be used to automate data backup and syncing across multiple apps. By following these steps and utilizing these tools, users can ensure a smooth transition to their new G Suite account and protect their valuable data.
