Modify mesh without losing skin. (3ds max)

astranime

I made a model for a game my brother is making, show it him and he said that it was fine so i skinned it and and made all the animations, when i finished he said if i could change the shape of the character a bit.
I dont need to add topology just move some stuff around, not sure if it´s even possible but don´t lose anything asking.
Hope someone could help me with this

Look into the Skin Wrap modifier. You can edit a clone of the mesh and use Skin Wrap to transfer the weight to the new model.

Oh i think a found another solution
While i was doing the skin wrap you told me, i edited the model and copied the skin modifier from the old model to the new one and works
Need to test a bit more but at the moment looks just perfect

Thanks for the help =D
