The disadvantage of updating the hints file in advance is that BIND will
moan gently that the hints file is out of step with the results of its 
priming "NS ." query (which, of course, it will subsequently use in
preference anyway).

I would leave any action until 1 December, myself. Not that the heads-up
advance notice isn't useful.
