It's not a common operation, it shouldn't be a big problem for it to take a lot of time. I think getting the Message-ID's of all read articles is exactly the way to do it. It may bring back some articles that were expired on the old server and not on the new, but that's almost certainly better than hiding unread articles, or bringing back *lots* of read articles because the mechanism wasn't thorough. I've seen some perl code that operates exactly this way, though it only works on the standard .newsrc, of course.
