[K12OSN] Migrating from one server to another

[Tim Born]

I have been wearing out the pages on this article: Virtualize a Server 
with Minimal Downtime (http://www.linuxjournal.com/article/9942).
It has lots of great information about how to, among other things, take 
an existing machine and pull it into a virtual machine untouched, so you 
can slide it to new hardware.
