Did an oopsie, now I need help with my modlist and some other questions

So I had a 300+ modlist for the AE version of the game, but I wanted to play storywealth and decided it would be better to back the mods up so I could play them some other time

However I only backed up the files, not the zip, and now I'm not sure if it's okay to drag them back to a different profile on vortex

Does anyone know a way, I'm scared to bring them back and it corrupts something

Also, most of the mods I have for the AE version are like, weapons and armors, Dak's mods and so on, I know theres a way to use them on the older version, but I'm new to this and don't really know how

Another question, is there a way for me to easily switch between the AE version and the pre next gen version?
