I have a Dell server that is 6.5 years old and is running Windows Server 2003 for Small Business Server. This is the only server in my office so it acts as a domain controller, file server, houses the free SQL database as well as Quickbooks. It also controls DHCP and DNS. It has been causing us problems lately so we decided to buy a new Dell server.
Now I am tasked with migrating all the things the Windows 2003 Server does over to the Windows 2012 Std Server. I have never done this so I am seeking advise on the best practices, steps to use, etc.
I will put the new server next to the old server so copying all the users files over will not be an issue, but all the user accounts, printers, making this a domain controller, etc is puzzling me. Do I need to unjoin all the client PCs from the current domain and rejoin them to the new server's domain, and on and on...My goal is to get this cut over across a weekend, so when the users arrive Monday we are good to go.
Any help, pointers, etc are most appreciated.
