I would try to create a private namespace "oldmail"
http://wiki2.dovecot.org/Namespaces
with an imapc proxy
http://wiki2.dovecot.org/HowTo/ImapcProxy

I didn't test it, but configuration could look like this:

imapc_host = oldmailserver
namespace {
  type = private
  separator = /
  prefix = oldmail/
  location = imapc:
  inbox = no
  hidden = no
  list = yes
}

Daniel
