For what it's worth, we've historically done exactly this for mail
server migrations (eg to a host with a newer OS release). We'll shut
down Exim on both hosts, then move over pretty much the entire mail
spool. I think the only problems we've sometimes had was needing to
reset the retry database(s). This does require a downtime on both
sides, though, and we've always been moving to a destination host where
the spool was empty (and in fact was disposable).
