You can always assign the same joints and then copy the weighting from your old mesh to the new one but, I am not sure... There are a couple options under there, "closes point on surface" normally does the trick. Someone feel free to correct me if I'm wrong, but check to make sure everything has UVs...

Great update...

I also said as above the best way is to use a Wrap Deformer.
You have to hide the geometry and make a new one for the different smooth level.
