Migrating from Kali sana (2.0) to Kali rolling is simple. As root, you can run the following commands and be on your way:

cat < /etc/apt/sources.list

deb http://http.kali.org/kali kali-rolling main non-free contrib

EOF



apt-get update

apt-get dist-upgrade # get a coffee, or 10.

reboot

Please note that the Kali sana repositories will no longer be updated and will be EOL’d on the 15th of April 2016.
