You cannot have both machines run at the same time connected to the  

What should happen:

* install LON-CAPA on the new server as "standalone," using a new IP  
address and DNS name, and test it
* shut down LON-CAPA services on the old server (stop all services)
* shut down LON-CAPA services on the new server (stop all services)
* transfer /home
* transfer /etc/httpd/conf
* completely shut down the old box and/or unplug it
* rename the new machine to the same DNS name as the old
* either
   - switch the IP address of the new box to be the same as the old
   - switch the DNS entry
* reboot the new box

It's a cumbersome procedure - am I forgetting anything?
