Out of curiosity, I've attempted an upgrade from Ubuntu 12.04 LTS, after a backup. I've never done an upgrade before, always clean installs, but I wanted to try and see how it goes, for experience. I've read this webpage:

After a backup, I started the upgrade ( sudo apt-get dist-upgrade ). Then I got a few errors at the end, I guess. After a reboot, LightDM was not showing the Ubuntu 13.04 logo, but still 12.04. Logged in, then I realised that probably broke Compiz / Unity / Nautilus. According to the system monitor, I was on Ubuntu 13.04, but had no way to verify.
Well, that wasn't a very good experience for my first upgrade (Wasn't expecting anything great. Just curious)! I do realise I've tried to skip 12.10, actually, for the upgrade. Maybe that wasn't a good idea.
Anyways, I restored my Ubuntu_OS partition, everything look fixed. But I stupidly replaces my Ubuntu_Home backup (I've realised I've done a second backup of Ubuntu_OS and erasing my Ubuntu_Home backup...), using Clonezilla...
I have a working backup of my Home directory 5 days earlier. I wouldn't loose a lot of stuff (That I could backup right now anyways), but I would like to be sure:
Did the messed-up upgrade modified anything in the Home directory?
Everything is running fine, now..
I did tested Raring from a LiveCD, and it look good - maybe I'll just install it next to Precise.
