We currently have 2019 Server Essentials .. we have purchased a new Windows Server Standard license and we are trying to upgrade in situ.
Have tried this command from both elevated command and also elevated Powershell ..
DISM.exe /Online /Set-Edition:ServerStandard /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX /AcceptEULA
.. error message "The specified product key could not be validated"
This command:
DISM /Online /Get-TargetEditions
.. responds with "ServerStandard"
This command:
dism /online /Get-CurrentEdition
.. responds with "ServerSolution"
The Server Essentials license was purchased from a retailer. The Server Standard license was purchased from a reseller and is VLSC.
Perhaps the current Essentials license needs to be "upgraded" to a Volume License version of Essentials before we can upgrade to Standard?
I am really hoping we can get this dism.exe working and don't have to build a new server and domain .. Any suggestions please?
cheers
