The company I work for is going to be merging with another company and their network. The new company has an IP scheme that over laps the one that we use for our Windows 2003 servers. Around 100 servers in all. We will be connecting to the new company by external trust and then eventually moving all servers and computers to the new company's domain. I have been asked to change all the IP addresses on all the servers in order to expedite the move. My main concern is the Domain Controllers and the Exchange 2003 Cluster. Does anyone have any experience with this type of situation? I am open to any suggestions on this.

You can change the IP address of the DC and EX if required.
