I currently have a free Google Apps for your Domain account, with only one email address in there. I will soon be moving from Google Mail to another hosted email solution (such as a hosted Exchange server).
As a result of this, I want to remove the "Google Apps" part from my domain, but retain all of the other services I use, such as Analytics and Webmaster Tools. This would need to move to a Google Account, with the same name as my current Google Apps account.
How can I do this?
