The correlation dynamics is investigated for various bi-partitions of acomposite system consisting of two qubits, and two independent andnon-identical noisy environments. The two qubits have no direct interactionwith each other and locally interact with their environments. Classical andquantum correlations including entanglement are initially prepared only betweenthe two qubits. We find that, contrary to the identical noisy environment case,the entanglement and quantum correlation transfer directions can be controlledby combining different noisy environments. The amplitude damping environmentdetermines whether there exists entanglement transfer among the bi-partitionsof a composite system. When one qubit is coupled to an amplitude dampingenvironment but another one to a bit-flip one, we find a very interestingresult that all the quantum and classical correlations, and even theentanglement, originally existing between the qubits, can be completelytransferred without any loss to the qubit coupled to the bit-flip environmentand the amplitude-damping environment. We also notice that it is possible todistinguish the quantum correlation from the classical correlation andentanglement by combining different noisy environments.
