    Always remember holes are made when bounded electrons break their bonds. means electrons in the valance band creates holes , not the electrons present in conduction band because they are already free ( are not part of any bond). The hole movement concept is realized in literature to accurately model and define semiconductor physics. as in reality only electrons move .

    answer is in your question. VKP is right. let me present this in a mathematical way. if you have a electron at (x,y) coordinate, and if it is moved to (x+5, y+5), you will have a free space at (x,y)... this is a hole. so, when an electron moves from its current coordinates there will be a hole. there is no such thing like hole movement.
