proxy setup for PI 7.3 single stack

Hi ,

Proxy setup for PI 7.3 single stack is to be done.

i have sap system which is already connected to PI 7.1 (old PI system). I want to make proxy connection of One sap system (ABC) to both PI 7.1 & PI 7.3 single stack system.

i have documents which mentions one SAP system to One PI system. Pls advise on it how one sap system can be integrated to multiple PI systems ( 7.1 & 7.3 ) using proxy.
