I have full passwords for all accounts.
So I setup the accounts on the gmail server via some type of web interface, right?
And I need to tell it I want it to synch up with the current imap server?
Then I change the MX records.
Then I press "GO".
And magic happens, it sucks up the local store to the cloud, and done?
Can I still keep the old email server in place and use it for outbound but not inbound? I should be able to leave it in with a low priority MX and it'll never see an inbound message. Maybe. I should block inbound just in case. Bounces will go to gmail.
