Keeping LCD config files when going from Volumio 1.5 to 2.0

Hi everyone!

I want to update to the latest version of volumio, but I am a little bit lazy and it costed me a lot of time understanding how to properly do it the first time to get things perfect for my taste. Specifically the LCD display whicih I really want to keep the way it is, is there an easy way to do this? Or will I have to spend a lot of time around forums to get my head around that?
