Business partner Initial Download

Question

Here is description of Business Partner setup:
CRM - Account groups - Prospective - Soldto
                                        Soldto
                                        Shipto
ECC- Account groups - soldto
                                       Shipto
There are some more but in order to ask my question i have listed few:
We are converting data from Legacy system and it is new SAP ECC/CRM Implementation
We are going to create Prospective in CRM will replicate it to ECC under classification Prospect
In ECC we will do account group switch from Prospect to Customer keeping business partner id same by defining same number range for Prospect and Customer account group in ECC. By middlware enhancment we will replicate customer to CRM and change prospect to Customer in CRM keep same business partner number.
My Question is for Legacy Data conversion:
Data conversion strategy is to load data to ECC system and then do Intial download to CRM.
My concern is how does initial download work in terms of numbering the BP. I am going to load all customers in ECC and download to CRM.
Once we are done with initial download we will fall back to strategy of creating prospect in CRM and later doing account group switch in ECC to customer so number range in ECC is external for customers. But for data conversion legacy system is going to hit ECC -- How do we control number range ?

Hi Murali,
As backend ERP system was a pretty old system, we had to implement 1067977. After this, the Middeware was working fine.
Sunil,
You could try implementing this note to solve your problem
