Exchange the black knights with the white knights as shown in the topmost big illustration in the minimum possible number of moves. One move is a normal knight's move on any vacant cell of the board.

The bottom diagram shows some moves of the chess knight which may be done as follows:
a - one cell in one direction (horizontal or vertical), and then two cells in other direction (vertical or horizontal);
b - two cells in one direction (horizontal or vertical), and then one cell in other direction (vertical or horizontal).
