I have transferred my entire CS fleet to P3D.

The 2 biggest issues were gauges & dll references.

I used the panel.cfg file to make sure gauges were put in the proper P3D gauge folder and correcting the dll.xml file to reference CS dll files.

Don't forget the effects files also.

Works good for me.

Seems that is all that is necessary is allow the installer to use the P3D as a root for direct installation.

I have a few other items to address, not CS related. When I accomplish those I will be shutting down FSX and use P3D exclusively.
