I don't have an easy place to upload images to but here are a few tips...
1.The instant 3D button Must be pressed. It will not work if you are not in instant 3d mode.
2. You can drag the feature from the feature tree of the old part to the face of the new part.
3. If you are trying to drag the feature itself you must grab it at the center of temporary origin. You can't just grab a face and drag.
4. If you have any constrsaints it will ask if you want to delete them or leave them dangling.
I wish I could be more help, but in almost a decade of Solidworks I have never used this command once from part to part until you asked.
It works for me though, so I'm sure it will for you too.
