RP/SE CRR Setup between Two local arrays and One remove array

Hi Team,

Need your suggestion/guidance on below scenario

At present, RP/SE CRR is implemtened between CX3-40 and NS120.

CX3-40(local site) is replicating to NS120 (Remote site) - Implemented RP/SE CRR,

We have installed VNX7500 at local site and connected some of the servers to VNX7500,

Now we want to configure RP/SE CRR between VNX7500 to NS120 along with the existing CX3-40,

means Two local Arrays(CX3-40 & VNX7500) and One Remote Array (NS120).

In near future, we migrate Data from CX3-40 to VNX7500 at local site in phases and will remove the CX3-40 and finally

we will be having  VNX7500 at local site and NS120 at remote site with RP/SE CRR implemented.

Could you please guide me, what is the best approach and Is RP/SE supports Two local/source Arrays?

Thanks in advance...
