How much old caulk to remove?

I'm redoing the caulk in my bathtub/shower. I've removed the old caulk in the horizontal seams between the tub and the tiles. But what about the caulk in the vertical seams where the tile walls meet each other? Do I have to remove all the caulk up to the ceiling? It's in good shape, can I leave it? If I do, will this compromise the seal in the corners where the horizontal new caulk meets the vertical old caulk?
