Migrating customers to BP

Hi All,

We are planning to implement FSCM Credit and Collections. The client has 4.6c systems and now implementing ECC6.0. Now, my question is, when we migrate all customers from 4.6 to 6.0, do we migrate customers to AR master data and then build a link from customer master to BP or directly create all customers in 4.6 as BP in 6.0.

Could someo

Regards,

Satya
