The Microsoft Key Management Server (KMS) is part of the Microsoft Volume Activation 2.0 solution managing Windows OS activation keys and performs activation for supported clients automatically. Starting with Windows Server 2008 & Windows Vista, Microsoft switched to an online activation system where every Windows OS requires activation. KMS shifts the activation requirement to a single machine which is activated with a special KMS Host (server) key. Every KMS supported Windows version automatically communicates with the KMS server to activate Windows and manage the activation key (configuring the Windows OS with a KMS key forces it to find a KMS Host and get activation from it).KMS supported clients include Windows Server 2008, Windows Server 2008 R2, Windows Vista, & Windows 7.

A single KMS Server can handle the load of a large enterprise and it is not likely necessary to install a second (or more) KMS Server. Many organizations choose to install 2 KMS Hosts to ensure license activations continue with the loss of a single server. However, going through the KMS Host activation process on an isolated network (not directly connected to the internet) is a time-consuming process. For this reason, it is recommended to use a server for KMS that can be easily restored from backup without affecting other services (this way the KMS Host key is restored on the same hardware).

There may be cases in which you simply want to keep your Windows Server 2008/2008 R2 server on-premises and upgrade it to a supported version of Windows Server and keep existing application installations in place. In this case, the in-place upgrade will most likely be the easiest option.
Below is a screenshot of the Windows Setup dialog box, which opens when you run the Windows Server 2012 R2 installation media from a Windows Server 2008/2008 R2 server. Click Install Now.
With the end of support from Microsoft for Windows Server 2008/2008 R2 reached as of January 14, 2020, moving production workloads off Windows Server 2008/2008 R2 should be a priority. While there are several ways to move your workloads to newer versions of Windows Server, the in-place upgrade may be the best option for those who want to keep their server on-premises and who have many custom applications, settings, and data that would be difficult to migrate to a different server.
Great article. I mistakenly installed enterprise edition and configured server and it came into operation and later found that i installed unrequired edition and after searching through find this article thx you make my life easy and saved from big trouble.
windows 2008 server evaluation, i am trying to upgrade my server eval copy as my origional server disk is damaged, however i have set up my server and as i normally do, i have insalled adk, then when trying to run dism /online blah blah, i get a returned message dism doesnt support servicing windows 7 windows 2008 server.??
You mention that the server you are upgrading using this method CANNOT be a Domain Controller. Why is that? I have successfully tested this out on a Windows Server 2008 Standard R2 to Enterprise and it worked fine. Just curious as to why it cannot or should not be done on a DC
If i were to upgrade my existing windows server 2008 R2 Enterprise server to windows server 2012 i would first choose the edition and then i would check the upgrade paths. I have created a table which shows whether you can upgrade to windows server 2012 with you present operating system.
Lets take a look at hardware requirements for upgrading our server to windows server 2012. Windows Server 2012 requires minimum of 16 GB to 32 GB of disk space. When you install Windows Server 2012 it occupies 15.1 GB of space approximately but its good to allocate at least 32 GB of drive space for Windows Server 2012. You would require 1.4 GHz 64-bit processor, 512 MB of RAM, 32 GB of disk space, DVD Drive, Super VGA (800600) or higher resolution monitor, keyboard and mouse.
In this post i will be showing you how to upgrade a windows server 2008 R2 Enterprise SP1 to Windows Server 2012 Datacenter. Note that the existing server is in workgroup, do not consider this post to upgrade your domain controller to windows server 2012. I will be creating a separate post to show the upgrade of domain controller running on windows server 2008 r2 to windows server 2012.
Goog morning Mr. Desai, I need a some support on my -upgrade Windows server 2012 R2 Std Edit. from 2008 R2 Std Edit., the thing is that I been trying for days and every time I get the CMD screen, I already tried all that I found in google but nothing works, could you be so kind and help me here please, what am I doing wrong?Thank you so much in advance for your kindness
Hi Prajwal Thanks for this article but do you have any article for how to upgrade server 2008 R2 Domain controller to Server 2012 with Role transfer? I mean if the we have working domain with server 2008 and if I would like to upgrade what are the correct processes?

Thanks for the informative posts Prajwal. Months ago we started a small project and it quickly became substantially larger. We have a terminal server that is 2008 R2 Foundation because we felt we would never need more initially. We need more so I bought Server 2012 so we could upgrade in-place and downgrade back to 2008 R2 so we can use the extra CALs we bought.
You can perform an in-place upgrade of Windows server 2008 R2 SP1 (STD/ENT) to Windows Server 2012 (STD/DC). Note that you must have Service Pack 1 installed on your Windows Server 2008 R2 first. Upgrading Server Core installation of Windows Server 2008 R2 to a Server Core installation of Windows Server 2012 is not yet supported. Also Windows Server 2012 requires a Windows Server 2003 forest functional level so check the forest functional level and set it to windows 2003 or higher than that.For more info, refer to this link :- _ServerRoles
The first and most important thing to know is that this upgrade has several stages. Don't expect to be able to put a Windows Server 2022 ISO into a Windows Server 2008 R2 server, selecting install, and have a fully updated Windows Server 2022 machine a few restarts later.
QuoVadis recommends enabling and using the TLS 1.2 protocol on your server. TLS 1.2 has improvements over previous versions of the TLS and SSL protocol which will improve your level of security. By default, Windows Server 2008 R2 does not have this feature enabled. This KB article will describe the process to enable this.
Enhancements in Windows Server 2008 R2 include new functionality for Active Directory, new virtualization and management features, version 7.5 of the Internet Information Services web server and support for up to 256[13] logical processors. It is built on the same kernel used with the client-oriented Windows 7, and is the first server operating system released by Microsoft to exclusively support 64-bit processors, a move which was followed by the consumer-oriented Windows 11 in 2021. Windows Server 2008 R2 is also the last version of Windows to support Itanium processors; its successor, Windows Server 2012, supports x64 processors only.
Seven editions of Windows Server 2008 R2 were released: Foundation, Standard, Enterprise, Datacenter, Web, HPC Server and Itanium, as well as Windows Storage Server 2008 R2. A home server variant called Windows Home Server 2011 was also released.
Windows Server 2008 R2 supports up to 64 physical processors[25] or up to 256 logical processors per system. (Only the Datacenter and Itanium editions can take advantage of the capability of 64 physical processors. Enterprise, the next-highest edition after those two, can only use 8.)[26] When deployed in a file server role, new File Classification Infrastructure services allow files to be stored on designated servers in the enterprise based on business naming conventions, relevance to business processes and overall corporate policies.[27] 2ff7e9595c
