I just upgraded from 25.10 to 26.04 LTS. I followed someone's advice to mv $HOME/.config to $HOME/.config.prev and was not too surprised when I lost all my kde configuration.
So I went through all the files and directories in $HOME/.config.prev, and mv'd any that seemed missing or changed from my previous settings into .config, and then rebooted.
My carefully setup configuration is still lost.
I copied .config/plasma-worskpace, but I nonetheless have lost my workspaces.
I have none of my changes to my panel(s). But then, I have no idea where they were stored, and might not have copied the right thing/hand merged it correctly.
etc. etc. etc.
This was supposed to be a caution against potential upgrade breakage. Instead, it *created* breakage I really didn't want, and hand merging the files didn't fix things as I'd been told to expect, in part for lack of comments explaining the various files.
I strongly advise other newbies to ignore the advice about moving .config for upgrade "safety". As far as plasma and probably other programs are concerned I might as well have done a fresh install. If not moving .config gets you in trouble, the worst you'll have to deal with is a fresh install and recovering from backup. And what I just got feels almost that bad, given that my backups include a list of packages to "apt install" and "apt remove".
