I am still running the (very old) Kubuntu 14.04 and want to upgrade to Kubuntu 20.04. I plan to do this by simply installing Kubuntu 20.04 into some new partitions (logical volumes to be precise), since I have new space and delete the old installation once I am done with moving.
What do I need to consider when moving? Especially, what directories should I take with me, which shouldn't I?
Is there a good strategy or are there best practices, where I should look for program files that I might want to keep?
Are there (official) moving guides out there?
