I switched Jamie to raw several months ago and the first morning he did get sick.  But I attributed that to the fact that the food was cold and his stomach was empty (first thing in the morning) and he wasn't used to eating in the morning as he never touched his kibble till lunchtime.  And he did eat it really fast.  So the next meal I tore it into tinier pieces so it would take him longer to eat it and we haven't had a problem since.  Good luck with switching!
