Create Layer showing where moved to/from

Help Please!?!

On the image below the Blue Triangles represent original proposed points (layer 1). Due to various reasons, some of the preposed points have to be moved represented by the Red Squares (layer 2). The red arcs represent preposed point moves (layer 3)

I need to figure out how to create layer 3 using the X,Y's from layers 1 & 2 for future projects. Can anybody give me a quick way to do this? There are typically 30,000+ points to be moved per project so drawing the moves manually is not very practical.

Thanks in advance!
