on both P3D and Wilco websites they say these are compatible with P3D.  I have purchased the V1 and V2 a few years back but on the site it says only compatible with FSX.

 

Does anyone have this working, do I just re-install it in the P3D files instead of FSX.  Do I have to buy the migration tool, been trying not to if there is no need.

I have it, works pretty much fine in P3D v2 as far as I can tell.  I used EMT to install but you might be able to just point it to your P3D folder and make it work.
