Relication between NX4 and VNX

Hi There,

I need to perform a file migration between a NX4 and VNX file. I plan to use NAS Replicator as the method. The NX4 is running on 6.0.40-5 and the VNX is running on 7.1.74-5. Is this supported. From what I am checking, it is supported. Please help confirm. Thanks
