Planning to reinstall to latest LTS release to allow repartitioning of dual boot (made Ubuntu partition too small and get repeated warnings that I'm running low on space--fwiw, not possible to simply adjust via gparted to provide more disk space to Ubuntu partition).
Generally happy with my system config, so wondering which files/settings/etc should I save/backup to allow as seamless a transition as possible to new version. I wouldn't be updating unless I wanted to repartition to give more space to Ubuntu since it's my daily driver, so would ideally be running a near identical system after repartition and reinstallation.
Guidance as to the 'how' both before and after reinstall is appreciated as well.
