Evaluation Edition:
The version downloaded from the Microsoft Evaluation Center is equivalent to the trial version provided by Microsoft and can be used for free for a period of time. However, this version cannot be activated using KMS authorization or MAS permanent authorization.

Official version/Data Center version:
The version downloaded from the Microsoft License Center is marked with GLVK, which can be installed and supported directly with KMS GVLK license or MAS permanent license, etc.

Evaluation version conversion official version/data center version:
The evaluation version can be converted by entering the official version or data center version of GLVK, and after conversion, it can be activated using KMS authorization or MAS permanent authorization; in other words, it cannot be activated without conversion.

Windows Server Evaluation Edition (Evaluation) can be converted to a formal version (Standard or Datacenter) by activation keys.
I personally recommend using Change_Windows_Edition.cmd in the MAS tool to convert, which will automatically identify the current version and whether it can be converted. There is no need to look for GLVK, just press the numeric keys to convert.
