Converting Windows Server Evaluation to a Licensed Version 

How to convert Windows Server Evaluation to a Licensed version?

If you have installed an 'Evaluation version' of Windows Server 2022, 2019, 2016, or 2012 R2 in your test environment and later wish to transition the same server to your production environment without losing data or performing a fresh installation, you may need to follow the method outlined below:

You can freely convert between Windows Server Evaluation version to Retail/Volume/OEM Licensed version. The edition remains the same during this conversion. If you are starting with an evaluation version, convert it to the retail version first, and then you can inter-convert as described. To do this, from an elevated command prompt, run:

slmgr /ipk <key>

Where <key> is the appropriate volume, retail, or OEM product/license key.

Open PowerShell/Command Prompt as Administrator and write and enter: slmgr /ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

After inserting the license key successfully, write this command for activation: slmgr /ato

Note: You must have to have a brand new Retail/Volume/OEM license key for the activation. So be sure you have it or you can buy from this store too. For your information, we are Microsoft Partner since 2010 and able to issue any version of Windows and Windows Server.

Nothing works? Seems like complicated? Why not reinstalling the server over your current server? It will give you an option to keep old data while installing the server OS, please be sure to keep a backup before the process. 

In our experience, this issue arises only when the server was installed using a Microsoft-provided Evaluation License Key. If the server was installed without any key, the activation process is simple. Just use your purchased license key, and it will activate instantly. If you don't have a genuine license key for product activation and are looking to acquire one at the lowest possible cost, please visit us for Windows Server 2022, Windows Server 2019, Windows Server 2016, or Windows Server 2012 R2 and for unlisted products you should contact us.
