I need convert Windows Server 2019 Essentials to Standard version. On the Microsoft web pages (and more pages) I find manual for convert this version, but i have problem with command DISM. If I run the command from cmd.exe or PowerShell DISM write me error 87 " options is unknown. " I need options
DISM /Online /Get-TargetEditions
DISM /online /Get-CurrentEdition
DISM.exe /Online /Set-Edition:ServerStandard /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX /AcceptEULA

I was trying find options in manual, but this option are not in /? help options (missing) I was comparating version DISM with wersion from example on the forum. I have higher version. This server has been installed from oreginal DVD. Update this server no resolved.

    Try again but without .EXE
    Dism /online /Set-Edition:ServerStandard /AcceptEula /ProductKey:12345-67890-12345-67890-12345

    Hi there,

    If PowerShell is not working you can try out these methods.

    1- Clean install
    The simplest way to install Windows Server is to perform a clean installation, where you install on a blank server or overwrite an existing operating system. That is the simplest way, but you will need to back up your data first and plan to reinstall your applications.

    2-In-place upgrade
    If you want to keep the same hardware and all the server roles you have set up without wiping and reinstalling the operating system, you'll want to do an in-place Upgrade, by which you go from an older operating system to a newer one.

    3-Cluster Operating System Rolling Upgrade

    You can these options here https://learn.microsoft.com/en-us/windows-server/get-started/install-upgrade-migrate#license-conversion-1

    Clean install is it solve, but extreme possibility. Before buy licence key for Standard edition I was finding out optionst for convert Edition and I was assured, os it is possible.

    Yes, it is possible to do but not for this one in this broken state. Here one for older 2012/2016 but steps are the same for Server 2019
    https://learn.microsoft.com/en-us/windows-server-essentials/migrate/transition-from-windows-server-2012-essentials-to-windows-server-2012-standard

    If there were already a domain you wanted to preserve then you can easily do that.

    I'd use dcdiag / repadmin tools to verify health correcting all errors found before starting any operations. Then stand up the new 2019, patch it fully, license it, join existing domain, add active directory domain services, promote it also making it a GC (recommended), transfer FSMO roles over (optional), transfer pdc emulator role (optional), use dcdiag / repadmin tools to again verify health, when all is good you can decommission / demote old one.
