SAP PO Integration with ARIS 9

Hi all

We want to implement SAP Process Orchestration in our company , having already implemented SAP PI/XI and ARIS 9.

We want to inquire if we can use BPMN models from ARIS 9 in SAP BPM or can we directly integrate ARIS 9 with PI/XI.

What could be the possible architecture for the existing products and SAP PO.

We would really appreciate your professional advise.

Thanks & Regards
