About Google Apps Migration for Microsoft Exchange

This feature is not available in the legacy free edition of Google Apps.

Google Apps Migration for Microsoft® Exchange (GAMME) is a utility that migrates mail, calendar, and contact data from your Microsoft® Exchange Server or mail from an IMAP server to Google Apps. It can migrate your email from almost any type of mail server (including Exchange, Groupwise, and Gmail) to Google Apps.

There are three main steps to migrate your mail:

  1. Set 3 settings in your Google Admin console to allow mail migration (see below).
  2. Create a CSV file of the users you want to migrate mail.
  3. Download the GAMME tool and run it to migrate mail.
