The best and easiest way would be to create the new domain inclusive all mailboxes in Mailcow and to transfer all existing mails from old mailboxes to the new mailboxes with a sync job (imapsync). However, other data like addressbooks and agendas need to be exported from the old mailboxes and imported in the new ones. This can be done directly in SOGO.
