Currently we have two domain controllers in our organization that need to be replaced. My plan is to replace both of these with 2 brand new servers running Server 2003 enterprise. I also plan on using Different names for these new DCs. What I would like to happen is be able to add one newdc at a time and replicate all roles from the old dcs to newdc1 and then put newdc2 online and replicate from newdc1 to newdc2 and pull the olddc1 and olddc2 offline. I do not have experience with implementing domain controllers so I am looking for any good articles, tips, advice, etc.
