Thanks Wayne... I've filed this (in my 'tips-n-tricks' folder) for 
future reference.

However, since this won't be an ongoing thing forever, I'll just keep 
things the way they are now (same layout on both), then when I'm ready 
to flip the switch, stop dovecot on the new server, do the 
transformation, change the dovecot config and start it back up.

Then all I have to do is deal with the users complaining about all of 
their folders showing up as subfolders of the Inbox, and explain to them 
how to remove the INBOX. namespace prefix in their mail client (this is 
a system that was converted some time ago from an old courier-imap setup)...


Best regards,
