Old lua files

I want to redo my old engines .lua on new steam version. But if I can save some works answer me:

If I create a template Family engine and add a same renamed Variants .lua from pre steam version will it work?

If I try coping text editing Variant .lua files from old version?

Can I download somewhere older offline pre steam version and note variable to redo on steam version.

sorry, but none of the old files will be compatible with the steam release, you’d have to remake every engine

You can send me te engines as zip. I have a tool that exports the settings into an Excel spreadsheet, this makes it very easy to rebuild.

What would be the outcome if I will remake every engine? Is there any possibility of transformation?
