Clean upgrade

[mandoran]

Hello all,

I was just wondering if some wise person could give a list of the essential customizations to save before doing a clean install of a new version of Linux Lite. 

I've tried Aptik to prepare somewhat. I know some advise backing up the root and home directories, but that seems like overkill - surely there is a small subset of that that is relevant to changes one might want to keep and reinstall?

Thanks!
