There is some recent buzz (no pun intended) around Google’s release of their Google Apps Migration for Microsoft Exchange tool.  The tool does what you would assume from its name, or as Google puts it:

Now you can migrate email, contacts and calendar data from on-premise and hosted Microsoft® Exchange to Google Apps, whether you have just a few users or tens of thousands.

Feature Overview

  • Perform a centrally managed bulk migration of users
  • Selectively migrate email, calendar or contacts (or any combination thereof)
  • Migrate in phases for very large migrations
