How to migrate from one array to other using Vplex

Hi,

I am taking training in VPLEX. I have a question, If we connect one CX and one VNX to the Vplex local. What is the procedure for migrating data from CX to VNX through Vplex. What steps we need to follow.

Can you give me an answer for this. Links to any videos or documents are also appreciated.

Thank you.
