We predict new features for the evolution of noncanonical screw wave-front dislocations nested in diffracting light beams. The evolution equations for the location of single-charge dislocations are derived, and their consequences are elaborated by use of illustrative examples. It is shown that the dynamic trajectories of the vortices can be controlled by adjustment of the noncanonical strength of the input dislocations.
