Starting this week, we are making it easier for businesses to migrate email into Google Apps using our cloud-based data migration service. The data migration service can be configured via the Admin console to connect to your mail server and migrate email over to Google’s Gmail servers.
Notably, this means that those wishing to migrate no longer need to download migration tools and install them on local servers, moving the process entirely to the cloud. Google says that currently this service is only for mail, but that support for calendar and contact migration is in the works.
A support page for the service is also now online if you’re looking for more information.
