i host a number of client websites on my dreamhost account, along with email.
a few hours of website downtime is not an issue for these clients, and they don't even notice most of the time, but email is crucial.
dreamhost doesn't seem like a very reliable service, but low cost, and not reliability is why i switched in the first place. so i'd like to move my client's email to google apps, and that's where the problem lies. i have no idea how to go about an IMAP migration.
ps. i know my way around DNS and unix. i just dont know how to get existing IMAP folders/mails onto gmail.
