Moving DHCP to a new server
The story so far is that I am systematically moving, migrating or installing, applications and services from a W2K3 server to a number of W2K8R2 servers.
OK so I've got a variety of articles and How to's for DHCP, as that's the next service to migrate. As I understand it I can export the database and import on the new server. Or backup the database and restore on the new server. However, as far as I can see none of the papers mention doing this in a live network. Does the network have to be non-operational for the move to take place? I'm a little confused as to what happens to clients during the move. Also after (or before?) the move, what will I need to look at to ensure that all clients are pointing to the new server?
