The new server is ready and waiting; I have requested the swap-over to take place on Wednesday. Since this doesn't involve any changes to DNS, everyone should be working with the same copy, but this version will go read-only before this happens so that no moves get lost as the database copy takes place.
It's just that all the existing code and database has been moved to a new machine. So it should look exactly the same. Except it's probably about time I did another revamp, if only I had any time to do anything at all, these days.
