@charadon I moved to #KDE#Wayland on #archlinux in a new computer 2 weeks ago and that was precisely my approach: everything fresh, copy selectively from old computer. Things mostly work, few minor bugs here and there.
Now that I got things how I like them I will format the old computer and install Arch with exactly the same configuration. I even plan on sharing selective config files (e.g. some KDE config, like keyboard shortcuts) through Syncthing and then symlink them on each computer.
