Update:
We have the new site up and running. Sort of.
We can see that the posts have moved over. Which is good.
The bad is that the posts seem to stop in Early February of last year, so that's -- less than ideal.
We're going to try to run it again next Friday with a new database dump to see if it was just some weird fluke, because this is obviously not ideal. We would do it earlier, but there are very few available times that match up with when I can do it from work.
So. Yeah.
There's that. Carry on!
