It's more or less how I do it sometimes. Personally, I copy / and 
exclude stuff like /dev /proc /sys etc that you don't want copied. 
Shutdown every service you can before copying, or for less downtime I 
will do one copy to get the bulk of stuff across, then shutdown 
services, and do another copy - the second copy takes a lot less time 
as it's only changed files and your (now closed) databases being 
copied.
It's also how I normally migrate a physical server to a VM guest.
