Moving your data doesn't have to feel like rocket science. As always, we at Apps Admins love to empower our customers in area of digital transformation. Below our trusted Senior Cloud Engineer- Marvin has listed a step-by-step process on how to get your data moving with Google Data Migration Service (DMS) Tool. 


The DMS tool is a cloud based migration tool that helps you bring over all your email, calendar and contacts from whatever current email service provider you are using. The Google DMS tool has some advantage over the other google migration tools, since it is cloud based. This means that the tool doesn’t require a computer to run the migration since Google does this on the cloud from the legacy mail service to G suite.

Below are the data sources we can migrate from:

  • Microsoft® Exchange servers that support Exchange Web Services (EWS), specifically Office 365, Exchange 2013, Exchange 2010, or Exchange 2007 (to migrate emails, contacts, and calendars).
  • IMAP servers, including Gmail, Exchange 2003 and earlier, and web-mail providers, such as Yahoo!® (to migrate emails) and any other consumer base free email.

Below are the data that the DMS can migrate to the new account?

  • Email messages, labels, and folders, including emails from a Gmail account
  • Contacts
  • Calendar events and resources
