Moving from FNSKU to Manufacturer Barcode impact listing ratings and Subscribe & Save?

We are transitioning our products, per Amazon recommendation, from FNSKU to our manufacturer barcode. We manufacture all of our own products and sell in multiple channels so this is a big win for us. However, we tested sending in our first product and it created a whole new listing in Amazon. The new listing appears to have the same ASIN and FNSKU (with an extension after the FNSKU that says "stickerless". This looks like a whole new listing in inventory management. Will this new listing eventually have the same product ranking (we are VERY high), customer reviews and especially retain all of our Subscribe & Save members? Thanks.
