Windows Server 2019 Standard Retail Version

[Samsky]

Is the retail version of Windows Server 2019 Standard downgradeable to Windows 2016 Standard?

Thanks

Hi,

Volume Licenses can be downgraded and you can get the media and keys for the previous two versions via the VL Portal.

Retail licenses have no downgrade rights.

OEM licenses have downgrade rights but you are on your own to find the proper media.
