Since you are moving from SmarterMail to SmarterMail, you should be able to use IMAP to pull the data: e-mail, folders, calendar, contacts, etc.
Since you have SmarterMail admin rights to the SmarterMail web interface, you will have no problems adding services to the domains. If IMAP is disabled, you will be able to enable it, on a domain-by-domain basis, etc.
Best of luck in the move. There are several of us who can assist you if necessary.
