Google don't let Google Apps accounts convert/migrate to Gmail or migrate purchases between Google accounts when I last checked. It makes it very difficult to exit the Google system when I tried to migrate to Fastmail. I don't really trust Google to manage messaging long term. Their messaging products have changed so often, I gave up trying to use them.
