I haven't moved a cat for 19 years, but before that I moved Shasta three times without any problem. To my mind there are three basic elements:
Preparation: In these days/weeks before the move, talk to her lots about it, with whatever is her favourite kind of attention. While you are packing, she may be feeling anxious about this unusual activity, so interrupt yourself often to cuddle and reassure her.
The Day: Make sure her things are in the new place and settled, before she arrives, in a room you can confine her in for a day or more -- your bedroom is best especially if she sleeps with you. Have her things there -- her bed if she has one; your bed with the same linens that you took off it if she does sleep with you -- you can have fresh linens once she knows she is "home"; her litter; her food and water. She should go to the new place on the last trip there, so that you both stay. Spend a little time with her, before you tackle the chaos in the rest of the house.
In the new home: Keep her confined in that one room for whatever time seems appropriate. It could be as little as a few hours or as much as a few days, depending how soon she relaxes and gets curious, and how soon the rest of the house isn't a safety hazard for her. Then increase her territory and let her explore. During her confinement, spend time with her frequently and talk to her about this great new place that you are going to enjoy together.
I'm sure there are a bunch of threads with moving advice, and that others will have advice as well. To my mind, the single most important thing is to "keep her in the loop". Even though they don't understand every word we say, I believe they take their reassurance from our communication with them, and do pick up the concept that, while the upheaval is distinctly not nice, the world is not about to end and all will be well. Shasta always moved well -- in fact, each time it was easier than the last.
Good luck to both of you!
