PI 7.1 content can NOT import on PI 7.0

Hi,

I am trying to import PI 7.1 content on PI 7.0 which is not working. When I put the file in server, it is not recongnized by PI 7.0 import queue.

Is the the content of 7.1 can't be use in 7.0 version.

I also set the software component version properties "use of interface objects" as SAP Netweaver 7.0 and took the export. But, it is also not working. I am wondering that is this property then.

Please suggest if there is a way if somebody tried.

Thanks,

Srinivasa
