The worst part about moving to a new computer or app account is having to download and copy everything from your old stuff and move it to the new. With G Suite, though, you may not have to go to that trouble.
If you're a G Suite admin, you can copy over emails from almost any email account and bulk import your entire team's email, contacts, and calendars from Microsoft Exchange servers. Strangely, it can't copy contacts and calendars from other Gmail or G Suite accounts—but it can copy your emails just fine.
Just open the G Suite Admin page and select Migration, or go directly to admin.google.com/AdminHome#Migration. Select what you'd like to import, then click continue.
For email, select the mail server your company's old email account used. G Suite can import email from other G Suite accounts, standard Gmail accounts, Microsoft Exchange, GoDaddy, or most IMAP servers. With all except for Gmail accounts, you'll then enter your admin login credentials for that server—and Google can import everyone's accounts at once.
You might not want everything—junk and deleted emails might not be important, and maybe you only want the most recent messages. Set the settings you want for your team's import, and then continue.
All that's left is to match up your accounts from the old server to your new G Suite account. With Exchange, IMAP, or G Suite accounts, you can do that in bulk by uploading a
.csv file of the old and new email accounts.
If your team previously used personal Gmail accounts, you'll need to add each person individually from the + icon on the page. Enter their Gmail account and their new email account in your G Suite. Then, tap Authorize and sign in with theirGmail account—or, click Authorize, copy the link, and send that to your team for them to sign in on their own. Either way, you'll get a unique code that's valid for 10 minutes. Copy that, add it to the G Suite migration wizard, and then Google will start copying over emails.
That'll take a while—about an hour to copy over one old Gmail account in our tests—but once you're done, each user's G Suite email account will have all the messages they had before in their old email account.
Want to migrate your team's contacts and calendars? Just go back to the Data Migration page, select the correct item, then login to your Exchange server as before. You can only import calendar and contacts in bulk from Exchange, though—if your team used Gmail or another service before, each team member will need to import their own data with the steps below. The good news is, that's not hard, either.
