Switching formulas

Is it just as hard on baby to switch between Enfamil formulas? I wanted to switch from Gentle Ease to Enfamil Soy formula. We already tried Enfamil Newborn and nothing is helping with this crazy amount of spit up. Hopefully the Soy will help but wasn't sure if I should even try.
