Greetings.

I've searched for some help in the threads, but with no luck.
I've used

apt-get clean && apt-get update && apt-get upgrade && apt-get dist-upgrade

Some small updates were made, but /etc/issue shows

Kali GNULinux 1.1.0

How to make a propper upgrade to 2.0.1?
Do I have to re-image, since all my settings will be lost?
Other workarounds to install 2.0.1 with settings kept?

I don't have kali-full-install.

Also sound is not working, have alsa-utills installed, but I'm missing something.

Thanks!
