A) you want to remove the wine from the lees & crystals before the wine warms
up by any amount, therefore avoiding the redissolution of the crystals, and
B) When you rack to another carboy, it will be of the same size (presumably)
but since you won't have your lees (if you chillproofed before racking off
the lees.) This will provide you with the necessary headspace, or
C) if you do plan on filtering and bottling direct (which suspect you won't
be) you can go straight to the bottle if you've already aged the wine long
enough in your estimation.
