Actually, that too is incorrect... If the runway length/conditions are different and a different flap setting is required, V2 will also change in addition to V1 and Vr. So basically, depending on the length of the new runway and its conditions (braking action, winds, slope, etc...) all your numbers can/will change or they may possibly remain the same, depending on the situation.
