I have a domain with 2 DC's in it running windows 2000, I have been told to to upgrade this enviroment to 2003, my manager has stated that he believes that we should remove the dc that has the schema master role from the domain, create a seperate test enviroment and try a 2003 upgrade and domain rename as a test and then and put it back into the production network. My concern there is that is that is something goes wrong we would need to restore completely.
Also that this stage I don't know how long we would have this schema in a test enviroment for, there are no planned changes to the schema planned for the production network before the 2003 upgrade, but can we make the remaining dc in prod sieze the schema master role if orginal DC schema master has been removed from the nework ?
wouldn't we be better to backup the system state on that server and restore it to another test server that is not part of the production network.
can anyone advise what would be best practice in this instance ?
