sure! assuming the ressie was made thur CRO...just call 'em up...make sure you have avalibility fer the room w/the AP price..then make a 'new' ressie...they'll cancel the old one...if you've made a deposit via credit card...they should be able to 'transfer' your deposit..or they'll issue a credit and then a 'new' charge! Hope this helps!
For our trip in January, we were able to call and have the code we had booked changed to an AP rate while keeping the same reservation number.
