I just remove it all---then replace it. That gives you the option of sistering in joists--replacing plumbing and whatever else needs doing without the sub floor in the way.

Great! I was hoping that would be the case. I am researching cut methods. I thought maybe a trim saw or close cut saw of sorts. Have any recommendations on that?

Get a toe kick or electric flush cut saw.

If the new sub floor will be as thick or thicker than the old one---leave it 1 1/2" out from the walls.

That is easier --faster---and gives you a surface to screw blocking into to support the new subfloor.
