This sounds like a good plan to me. After you've shut down Exim on the
old machine (and renumbered/renamed the old host) and started up the new
one, make the following changes to the exim.cf on the old machine before
running "/usr/lib/sendmail -qff".

Set...

local_domains =

Add the following as the first router...

smarthost:
driver = domainlist
transport = remote_smtp
route_list = "* new.host.name byname"

... substituting the name of the new host in the last line, of course.
