If I remember right (I am work at the moment, so I cannot look for it), V3 comes with a V2-compatible extra CR2. You  can use that figure with V2-Clothes, but will not be able to use V3-Body morphs.

On the other side you can convert V2 clothes for V3, either with Crossdresser or with Wardrobe Wizard 2. Since I don't own Crossdresser I cannot say much about it, I do have Wardrobe Wizard and it works good, it even can fit the clothes to a morphed figure.

You will find WW2 at www.philc.net.
