First of all, I am an acknowledged neophyte when it comes to servers.
I am building a new Windows 2008 server for our school to replace an existing 2003 server.
It will be my primary domain controller, DNS, DHCP and Active Directory server. I have one already running on our network. I am assuming that if I install and configure these roles on the new server while it is on the network, I will experience conflicts and issues.
Do I need to disconnect this server from the network and configure it, import all my settings, etc and then when I am ready, just shut down the existing server and bring this one online?
Can I use the same IP address as the old server when I bring the new one online - that way it will be seamless to the rest of the network?
How do I test the new server when it is offline?
Suggestions of online resources that can guide me?
