DiskXtender Centera replica read

Hi All, I'm totally green when it comes to diskxtender and Centera. In my environment I have 2 Centeras which are replicated one way. To the PROD centera I have 3 diskxtenders connected. Now we have a migration project to migrate data of the Centera. I'm trying to find way to connect one of the diskxtenders to the second Centera (replica) and read from it. I only need to read the data. Is there a possibility to read data from replica when primary Centera is working? thanks Zbyszek
