Don't know how well the advice traslates to Exim, but on the Postfix
users list the standard advice for moving queued mail to a new server is
to configure the new server as a smarthost relay on the old, and just
transfer the queued mail via SMTP! (This may involve also configuring
the old server to not treat any domains as "local").
FWIW, moving queue files is also possible, but SMTP transfer is
preferred.
