This article is for IT administrators in Mac™-only organizations looking for tips on how to migrate their mail, calendar, and contacts to Google Apps.

To move to Google Apps, the simplest option is to not migrate your organization's old data and start new with Google Apps. This option requires the least amount of effort from your IT staff.

If you need to migrate your users' data, we recommend that you use Google Apps Migration for Microsoft® Exchange. This tool allows you to migrate data from your Exchange Server or IMAP-enabled email service for a few users to tens of thousands of users. However, you'll need to run this tool on a Windows™ computer. Learn more

If you don't have access to a Windows computer to run Google Apps Migration for Microsoft Exchange, you can use these migration tools for Mac:

1. Email Uploader for Mac
2. Mail Fetcher. Note: This tool doesn't migrate folders.
3. 3rd party tools on the Google Apps Marketplace

Note: These are client-side tools and only work with one user at a time.

Email Uploader for Mac

Email Uploader for Mac is a desktop utility that uploads email from Apple Mail, Eudora, and Thunderbird; and exported email from Entourage.

Requirements

Mac OS X 10.4 or later, and a Google Apps account for each user.

Using the uploader

Download the Email Uploader utility to each Mac your users want to migrate mail from. The Email Uploader utility is available on the Google Code site.

Google Email Uploader is available for all editions of Google Apps. Email Uploader queries are not supported by Google Apps. For detailed instructions and troubleshooting, please visit: Issues and Discussion Group.

The uploader will try to find your users' mail archives in their usual locations on Mac OS X:

• Apple Mail: ~/Library/Mail
• Eudora: ~/Eudora Folder
• Thunderbird: ~/Library/Thunderbird

Your can add mail search locations or upload exported Entourage archives using the File menu.

Tips:

• Start small. Migrate a small group of users' inboxes when first using the uploader.
• Be patient. Even after uploading completes, the Gmail server requires time to process uploads.

Note: Labels in Gmail function differently from folders in other mail programs. Learn more about labels in Gmail.

Troubleshooting

If the uploader doesn't accept your email address and password, check to make sure that User email uploads is enabled on the Advanced Tools page of your Google Admin console.

Gmail Mail Fetcher

Gmail Mail Fetcher is a tool that migrates mail from a Gmail or non-Gmail account to a Google Apps email account. In most cases, a user migrates their own mail using Mail Fetcher. However, an administrator with the user's login credentials can also migrate the user's mail.

Please note the following limitations. Mail Fetcher

• only migrates messages in the user's Inbox.
• does not migrate folders.
• changes the received date of all messages to the date of migration.

Use Mail Fetcher if your users do not have strict migration requirements, and have not archived their messages or sorted mail into folders.

Third party tools

Third-party web tools and migration services offered by Google Apps partners are available on the Google Apps Marketplace. Some of these tools and services migrate mail while preserving receive dates, folder/label structure, read/unread status, importance levels, and also migrate sent messages.
