Definitely consider moving her first, and if you can, bring her over to the new place - with litter box and food, of course, and sit with her for a while until she calms down. leave her some toys, but shot her in one room - the bathroom is fine - and put a big note on the door that says "DO NOT OPEN!!!" in case anyone is helping you move! If you have a little radio you can put in the room with her for some noise, that might help.

When my brother and his family moved, his cat got so freaked out by the process he managed to wedge himself into a gap between the floors when someone moved a box my brother had placed to block that hole. It took a couple weeks for him to emerge to the now-empty house, thankfully my Dad was around so folks could make visits with a little food/water, but Pip was one freaked-out boy!
