Transform view volume from one view into another

So i have an object in world space and two views A and B which display the scene with different camera setups. I want to transform the view volume (near plane) from view A into view B so i can have something like an overview and detail. What transformations do i have to apply to the points of view A's frustums near plane to display it in view B?

Let V_a be the non-singular, invertible transformation from world space into view space A. Let V_b be the non-singular, invertible transformation from world space into view space B. Then the transformation from space A to B is

T_A→B: r ↦ V_b · inverse(V_a) · r
