I migrated four separate Google accounts to a single Fastmail account last year. I had put off migrating for _years_ because I thought it would be painful, but I've had no issues at all. The migration was automated with good progress updates as emails are copied across. I had to do the DNS bits manually but they were nevertheless well documented. I've had zero issues since with mail, calendars, or their simple static site hosting. I think about it so little I sometimes forget how happy I was with the whole process.
