What i would try is make you bird want to switch cages, try to put all of his toys in the new cage and lots of treats in there.
leave him a few days between the two, and when he starts to sleep in the new cage make it official. as long as he's getting enough out of cage time and attention he shouldn't try to go back inside the other cage especially if its occupied.
if stuey tries to go back maybe on top and your cockatoo gets along with him just fine then its just a matter of your birds enforcing their territory.
the only way to find out is to try but you'll need time, but since you've already got the cockatoo maybe an extra 100 could get you a good deal on a cage just as big.
ideally i would buy a new big cage and NOT try to switch, but if you have to maybe try putting them in separate rooms if you can
good luck and keep us posted
