Windows Network Upgrade
Posted on 2005-03-03
I'm replacing our old Windows NT server with a brand new one running Server 2k3 this weekend. We have a relatively small network with about 15 client machines and are currently running Exchange 5.5 on an NT server which is also acting as the Domain Controller. All services are basically running in one box (exchange, NAV, backup), with one more box running ISA 2k as the firewall. My questions might be basic and to broad, but I'm basically asking what I should look out for while doing the upgrade.
What is the best method for doing the upgrade? Do I set up the new server as the domain controller, then attach the old server to that domain, then transfer everything over (files, exchange mailboxes, etc)? If I do this, don't I have to have a different domain name than the current one? How will this affect the client machines (all clients are win2k or greater)? I don't want to have to reconfigure every client machine just because I've changed the domain. In other words, If user A logs in as USER_A on OLDDOMAIN, then logs in as USER_A on NEWDOMAIN, will XP create a new "user" for that computer with whole new settings, desktop folder, my docs, etc? Is it possible to have the new server use the old domain name, and if I do this, will the change be transparent to the clients?
Also, what should I be concerned about in terms of moving the Exchange mailboxes?
Is there a standard "order of operations" for this kind of thing?
Any help is be appreciated.
