Migrate mail from other Google accounts or IMAP servers
If you've created a new Google Apps account for your organization's email, you can migrate your data from your old Google account or an IMAP server, using one of the following tools:
- The data migration service is the recommended way to migrate mail. It's clientless and cloud-based and easy to set up and monitor. You do everything in the Google Admin console.
- Google Apps Migration for Microsoft® Exchange (GAMME) is a utility that migrates your mail, including labels and archived mail, to another account. GAMME can also migrate other data, but requires you to install the tool first.
- You can also check out the Google Apps Marketplace to review other migration solutions provided by third parties.
