Upgrading from 11.10 to 12.04
I am running Kubuntu Oneiric Ocelot (information confirmed by lsb_release -a).
Instructions to upgrade to 12.04 just say "follow the procedure". I remember that once upon a time in order to upgrade there were many precautions such as disabling all the proprietary drivers (example: the Nvidia proprietary driver) and so on.
Are all these precautions now superceded?
