My dilemma is as follows;
I currenty have a Windows 2003 SBS which is the domain controller on our network. This has some accounts software and telephone management software installed, that software is incompatible with Windows 2011 SBS which our new server has installed on it, therefore the software has to stay put on our old server.
However I need to install the new 2011 SBS onto our network and get all the workstations moved over to the domain on the new server. I need to keep the domain name the same on the new server as all our workstations need to be able to see both the new server (for exchange etc) and also the old server for the old software.
Am I able to make our 2003 SBS act as a workstation instead of a domain controller, as once I have setup exchange on our new server the old server won't need to do any server related work whatsoever, it justs needs to be running on our network for access to the old software.
I've heard its possible to "demote" our current server making it a "secondary" server blah blah etc, but what I really want to do is to just make our current server act as a workstation, it doesnt even need to connect to the new domain or anything.
The future aim is as the new versions of our current accounts and telephone management software become available we will install them onto the new 2011 server and eventually get rid of the 2003 server off the network altogether.
Any ideas would be greatly appreciated.
