My method of installing

[jetsmell 45]

I currently have FSX SE but will purchase the latest Prepared4 in a couple of days. This is how I would like to do this but let me know if there's a better way. I would un-install all of my payware aircraft, scenery, utilities, etc. and there's a ton of them. Next, purchase then install Prepared4. Finally, install only the payware that is compatible at this time. 

Right now my E: Drive is dedicated solely to the flight sim. My external hard drive ( F: Drive ) has all the Mega Earth Sceneries and have never had a problem with that. When I do the clean install should the Mega Sceneries be un-installed also? Thanks in advance for your help.

How many of your payware aircraft  are made for P3D V4?

I haven't checked but I have most of the PMDG, A2A, Carenado, Milviz.
