J or S

I've been seeing that the tranny fluid for Nissan has been changed to S from the J type. Is there any input on if I were to simply drain my fluid from the pan, if the newer S type would play nice with the older J type left in the system? I have to change my hoses for the tranny fluid cooler up front since they're leaking, so I figured since I'll be getting all tranny-fluided, I might as well do a simple drain and refill.
