If you are moving from a hosted email service (other than gmail.com) to Google Apps, Google is releasing a new migration tool. Partnering with TrueSwitch, Google is giving users the ability to migrate email from more than 50 different hosted email providers, automatically notify contacts of the new address, and forward email from the current provider to Google Apps. As a third party tool, Google is only providing “best effort” support.
While has proven effective for users of the free Gmail service, businesses may elect to follow other migration paths for the following reasons: (1) TrueSwitch requires end user action or access to every end user account through the interface; (2) while the tool runs in the background, you need to be logged into the user account to check status; and (3) the tool is designed around personal email accounts.
Businesses may prefer to use other methods and services designed to migrate domains, rather than personal accounts.
