Prepare Business Partner
Conversion 
Use
This section describes the steps you need to follow before beginning the business partner conversion.
Prerequisites
Before you begin with the business partner conversion, you should read all the documentation on this subject.
Procedure
...
1. Check whether SAP Business Partners already exist in your system, and how many Treasury Business Partners you have. To do this, examine the entries in table BUT000 for the SAP Business Partner and table BP000 for the Treasury Business Partner.

Ideally, you will not have used any SAP Business Partners. In this case, entries will exist in table BP000 and not in table BUT000. After you have carried out conversion phase I, the same number of business partners will appear in both tables.
If you are already using both Treasury Business Partners and SAP Business Partners, you cannot automatically assign the Customizing. The number range intervals for the Treasury Business Partner and the SAP Business Partner could also overlap. In this case, you must carry out conversion phase I with different numbers, and then create identical numbers in phase II.

You will find further information under Preparation and Structure of Customizing.
2. The conversion reports should be initial before the business partner conversion takes place. If this is not the case, change the status prior to conversion.
