Migrating from Windows Server 2003 to Windows Server 2008

This article presents a picture of how migrating from Windows Server 2003 to Windows Server 2008 is a complete process. This article assumes the following case:

The original Domain control situation is as follows:

Computer name: DC2003.itpro.local (FQDN)

IP address: 192.168.255.1/24 (dns:192.168.255.1)

Operating system: Windows Server 2003 Enterprise Edition SP1

Providing services: Domain control, DNS, DHCP

After the upgrade is completed, add Server2008 to the domain controller

Computer name: Server2008.itpro.local (FQDN)

IP address: 192.168.255.100/24 (dns:192.168.255.100)

Operating system: Windows Server 2008 RC0 Enterprise

Services available: Domain control, DNS

The above test environment, whether local administrator or adminstrator in itpro.local domain, login password is P@ssw0rd (note 0 is zero, not letter O)

Before we begin, we must install a server with an operating system of Windows Server 2008, which is not detailed here. If you do not have a Windows Server 2008 CD at hand, you can download the beta version to the MS official website.

After Windows Server 2008 installation is complete, modify the IP address of the local area connection to: 192.168.255.100/24,dns:192.168.255.1 machine name is Server2008 and Windows Server 2008 joined to the original Windows Server 2003 EE domain (itpro.local).

When completed, the operating system will require a reboot. After the reboot completes, log on to the member server Server2008 as Itpro\administrator. Before testing is done, let's look at the existing FSMO role scenarios. (Run cmd, enter netdom query FSMO)

Before you upgrade domain control to Windows Server 2008, you must make related extensions, as you would upgrade from a Windows Server 2000 domain to a Windows Server 2003 domain. Here we must run the Adprep tool for Windows Server 2008 on the original Windows Server 2003 domain controller, located in the Source\adprep directory on the Windows Server 2008 RC0 CD, please Adprep directory to any partition on a Windows Server 2003 domain control (the computer name is: dc2003), this case copies the folder to the DC2003 disk partition D.

Note: The original Windows Server 2000 domain was upgraded to a Windows Server 2003 domain, and only forest and Domian were extended, but in Windows Server 2003 domains upgraded to Windows Server 2008 domain, the RODC must also be extended so that Windows Server 2008 can act as a domain controller type role in a Windows Server 2003-based domain, and the RODC (full name read Only domain control) can be found Look at the topic of Windows Server2008 in this community or relevant information on the Internet.

Note: The following actions are performed on the DC2003 (domain controller).

Start-run-cmd, enter adprep directory input for D partition Adprep/forestprep According to the prompts, select "C" and press ENTER to continue.

Complete the forest extension. Next up is the RODC. Enter: Adprep/rodcprep (from the results shown, it appears that these extensions have been updated, but you cannot continue until you have tried to skip the RODC extension.) ）

After the extension of the RODC is completed, the domain extension is followed. Input: Adprep/domainprep/gpprep (note: For Adprep/domainprep/gpprep, see KB314649 and KB309628)

OK, we are ready to promote the Windows Server2008 (computer name Server2008) to a domain controller.

Now, log on to member Server 2008 as Itpro\administrator. Start-run-dcpromo (I'm sure you're familiar with this)
