    On the old server, dovecot is configured to just use

One thing you can do is to add a symlink on the sending side to point the Maildir to '.', and then run rsync with -R --no-implied-dirs and both the normal top-level dir and a path down to the Maildir/ (with the trailing slash) plus an exclude of the files in the user dir and the symlink itself. For instance:

mkdir -p /tmp/src/user
touch /tmp/src/user/{one,two,three}
ln -s . /tmp/src/user/Maildir
rsync -aivR --no-implied-dirs \
      --include='/src/user/Maildir/' --exclude='/src/user/Maildir/Maildir' \
      --exclude='/src/user/*' \
      /tmp/./src /tmp/./src/user/Maildir/ /tmp/dest/

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)...
