We propose a scheme for realizing entanglement transfer based on the cross-Kerr nonlinear interaction between field-modes. By using this scheme the entanglement can be transferred from the field-states with discrete variables to the field-states with continuous variables. By suitably choosing the amplitude of the initial coherent stateswe can obtain the maximum entangled coherent states.
