Upgrade the server domain environment to Windows Server 2003 domain environment upgrade to Windows Server 2013

What is brought to you today is the upgrade of the Windows Server domain environment, where Windows Server 2003 is used to upgrade to Windows Server 2012.

Let us introduce you to the specific process of Windows Server domain environment upgrade

First of all to introduce the experimental environment today: three servers, a Windows Server 2003 (SERVER04), a Windows Server (SERVER05) (here it is necessary to say, 2003 can not directly superior to 2012, Must be 2008 intermediary), one is Windows Server (SERVER01)

Three servers installed ad, here is not introduced, 2012 of the installation method, in the previous introduction, 2003 and 2008 of the installation method, as long as the operation in the execution dcpromo follow the instructions can be, and 12 no difference, there is a need for friends, can give me a message.

The first domain controller in this experiment must be 2003 because we are 2003 upgrade 2012,2008 and 2012 AD, which is 2003 additional domain controller.

Here also stressed that, after 2003 version, with 2003 there are some differences, that is, 2003 later version, added a read-only domain controller, which also resulted in, 2003 version of the server ad, if you want to add directly to the 2003 wrong domain, there will be problems

(Server04 on behalf of Windows Server 2003,server05 on behalf of Windows Server 2008,server01 on behalf of Windows Server 2021)

First, we need to elevate the functional level of the SERVER04 domain controller, open the AD Users and Computers, right-click, select All Tasks, raise the domain functional level

After upgrading the functions of the forest and the domain, you also need to execute some commands, mount the 2008 installation image to Server04, then execute the following command before you can join the SERVER04 domain, command line execution, command as follows:

When these steps are completed, the server05,server1 of the two servers to install the server04 of the additional domain controller, the specific installation process is not verbose, let us directly into the topic

The so-called domain environment upgrade, in my opinion, is the first to add server05 and Server01 to server04 domain, and then uninstall server04, uninstall server05, the remaining Server01, then, server01 the domain functional level, Is the functional level of the entire domain, also reached the domain functional level upgrade, so, in addition to at the beginning, server05 and Server01 added to Server04, there will be some problems in the end, uninstall domain controller, no big problem

All right, let's just uninstall the ad on Server04.

Before uninstalling ad on Server04, let's take a look at ad sites and services where the replication topology is normal
