Simplest movement to point possible

I have a cube, on a simple plane…

The cube is at position 5.6.7.

i have an update function in javascript.

What is the easiest way to move the cube to position 2,3,9 over a period of 2 seconds?

var time =0.0;

   function Update() {
       time += Time.deltaTime;
       transform.position = Vector3.Lerp(transform.position, Vector3(2,3,9), time / 2);
   }

You would need to reset time to 0 if you move the object and wanted the movement to happen again.

From the documentation:

function Update () {
    transform.position = Vector3.Lerp(start.position, end.position, Time.time);
}
