In my experience if it's the same brand food with same protein based formula then I do a straight switch. I haven't had problems with that.
I recently switched Troy from Merricks Chicken Grammy Pot Pie recipe to Blue Bluffalo Chicken and Rice. Although I did the 50/50 with this Troy ate around the Merricks. No loose stools but horrendous gas. We've been on it a 4 days and I give it a thumbs up thus far.
