2 Objects Vetrax lerp ?

I have 2 pretty much the same objects.
The same number of vertaxes, very similar possition, corespodning vertaxes are in the same positions in vertax list.
I move all vertaxes in one object around, I want to select some of that vertaxes and take their positions and asing their positions to coresponding vertaxes in secondobject.

So 1objects moves, and second objects inheris some movement form 1 objects

I would like also to create some interpolation between 1 object and 2object.

Mesh.vertices will get you access to the vertices. Vector3.Lerp will get you linear interpolation.
