Does anyone see any problems with this scenario. The completed task will be to upgrade an existings 2k domain with a 2000 exchange server to completely 2003. To get thru the exchange part we want upgrade exchange to 2000 running on windows 2000 to exchange 2003. Then introduce a new server running windows 2003 and exchange 2003, then remove the first exchange(W2k now w/ e2k3) from the network. Then add all new servers (just because we needed a hardware upgrade anyway) that are running 2003 and we will then have a completely 2003 domain. This right now is our primary scenario, any flaws?
