pfff, I hate doing a clean install, although I know it is the best thing to do.
But that means, start copying all files, ... to discs.
Install, and then reinstall all files again.
It'll take weeks before everything is back in place.
I guess most of you know what I talk about. You install the most important stuff again, and from time to time you say, damn where is that app/file again, then you have to look for it on the back up discs you made.
I had the same issue with X.1, I did a complete install, and afterward I found myself days/weeks finding out small stuff that had to be copied again.
But OK, Jag is worth😀
