You could try letting her play in the new cage a few times before doing the swap & when you do change keep all the substrate, nesting material, even some food hoard so it all smells as familiar as possible, move her house, wheel & toys over & if possible keep the layout similar.
The main thing is to give them time to adjust, some can take a couple of weeks & it's best not to interfere in that time, don't keep changing things unless something really isn't working, just do minimal spot cleaning & only interact if she seems keen until she's had time to make herself at home again.
