Well the title is "The Wrong Way to Switch Operating Systems on Your Server" so it's unsurprising that it's describing completely the wrong way to do things.

Yep, the correct title would be "There is no Right Way to Switch Operating Systems on Your Server" Just don't do it. Fire up a new one, and migrate everything over.
