OrCAD 16.3 dsn Format is not opening?

Hi...

I had drawn the schematic in OrCAD 16.3. but it was not opening in the OrCAD 9.2.But i read that in the forum, that want  to save  the format in previous version of it. 

So I dont know how save the previous file format. So can anyone provide me the right solution to save the OrCAD 16.3 dsn to OrCAD 9.2 dsn.

Thanks & Regards,
