We have a domain rename ahead of us and need some advice. Here is our situation. Our current domain - abc.def.ghi.com is being renamed to xyz.def.ghi.com. Our environment is Server 2003 EE, Exchange 2003. We also have a myriad of other parts that depend on the domain - websites, web apps, oracle databases, Solaris environment, etc. What is the best way to approach this? Do we change the domain by using the MS domain rename tool, and then change everything else? Or do we create the new domain now, and migrate everything (AD, Exchange, Solaris Environment, Web apps) piece by piece.
Thanks in advance for the advice.
