I have an existing e-mail address (hosted using Exchange) that I use for my Google account (for Calendar and Docs, etc.) and now want to enable e-mail on that account as well. I've found information on how to migrate account contents once I've enabled e-mail, but it's not clear from what I've found how to enable e-mail in the first place.
Starting from a state where I have an existing Google account for
firstname.lastname@example.org (for Calendar and Docs, etc.) with the e-mail address hosted on Exchange, how do I get to a state where
email@example.com is hosted fully on my Google account (Mail in addition to Calendar and Docs, etc.)?
(If it matters, the next thing I'll want to do is "upgrade" to G-Suite with
firstname.lastname@example.org as the Super Admin.)
