Multiple ERP backend system for SAP CRM

Dear All,

We have a requirement, Client want there SAP R/3 upgrade to SAP ECC to happen in phases based on small regions. Now we have to sync master data with both SAP R/3 and SAP ECC. The same objects like Customer, material , Vendor should replicate to different backend ERP system based on region.

Kindly provide your inputs, if this scenario is possible.

If yes, Kindly provide SAP note or blog.

We have referred the SAP Notes : 1763516 , 1084315 and related Notes, but it is not clear enough to confirm a solution for customer replication to 2 different system based on region.

Help will be appreciated.

Many Thanks,
