You can drain and fill, the fluids are compatible. Each drain and fill takes out 3 quarts (some transmissions it's closer to 4) and the entire system has a 12 quart capacity, I recommend doing it at least twice with driving in between to mix the fluid but realize that you're draining out brand new fluid with the old once you do it a second time. Doing a flush has the same effect, it takes more than 12 quarts if you are trying to go for brand new fluid in the whole system.
I did it 3 times when I switched to synthetic. I replaced approximately 60% of the fluid doing it that way.
