I am hoping someone will be able to give me advice on how to proceed with my project. I am installing vinyl flooring and noticed the particle subfloor was rotten in a spot. I decided that I wanted to remove it and replace it with plywood. When ripping it up it looks like it was screwed and glued onto risers (planks of wood – not sure what they're called).
Is it best for me to take these risers up and just place 3/4" plywood on top of the existing plywood? I assume I would have to glue as well right? Or should I get 1/4" plywood and lay that on top of the risers?
Any advice you could provide would be greatly appreciated as I clearly have no idea what I am doing. Here is a picture of what it looks like:

Thanks in advance!

If I were you I'd keep those risers there. You don't know if they're glued on the bottom and you might damage the plywood underneath. Sand those risers to get rid of the glued particle board remaining on them. Then replace the particle board with plywood of the same thickness and make sure you glue it to the risers in addition to using a fastener. Fastener does all the structural work and the glue prevents squeaky floors.
