Initial Exchange 2003 Server Installation
You can't directly upgrade an existing Exchange 5.5 server to Exchange 2003. Once you've installed the ADC, select a site and install an Exchange 2003 server in that site. For best results, select the site that acts as the hub of your current organization.
The steps to install the first Exchange 2003 server in an existing legacy Exchange organization do not differ much from those that install an Exchange 2003 server in a pristine organization. Refer to Chapter 1, "Installing an Exchange 2003 Server," for the detailed installation steps.
The Exchange 2003 prescriptive checklist includes provisions for installing the first Exchange 2003 server in an existing legacy Exchange organization. Don't forget the prerequisite services on the server:
IIS Admin (Iisadmin)
Once you've installed the Exchange 2003 server, you should do some provisional testing to ensure that your migration infrastructure operates satisfactorily.
The primary differences in the installation of an Exchange 2003 server in a legacy organization occur in the background. Setup does the following:
Replaces the placeholder name on the Organization object in Active Directory with the name of the legacy Exchange organization.
Installs a Configuration Connection Agreement in the ADC that links the legacy Configuration container to the Organization container in Active Directory.
Enables and starts the Site Replication Service (covered later in this chapter).
A short time after Setup completes, the Recipient Update Service places the newly installed Exchange server into the Exchange Domain Servers group.
Drum roll. Cymbals clash. You did it. You installed the first Exchange 2003 server in the legacy organization. You have a lot of work ahead of you, but for right now, you should test the system to make sure everything works right so far.
