I hope my recent experience applies; I just took a flight last week using AS miles, redeemed on CX, and wanted to put in my AA number for the benefits. The AS agents I interacted with (the original booking + date change) couldn't change/replace/remove my AS number. My guess is that it has something to do with being tied to the miles coming out of my account.
So I simply got the confirmation numbers for CX and used the CX website to update my FF number. I did notice that when I changed my booking, the AS number went back into the record; just had to go back in and put my AA number again.
