I had to find a way to upgrade a server from Windows Server 2012 R2 Standard to Windows Server 2012 R2 Datacenter Edition. A colleague did the installation of the Standard edition instead of the required Datacenter...

So the question was : how to convert a Windows Server Edition from Standard to Datacenter, without having to manipulate offline ?

After some researches, I found the solution to my answer. I had to use the DISM command, with this syntax :

dism /online /Set-Edition:ServerDatacenter /productKey:<valid datacenter PK> /AcceptEula

After a reboot, my server was finally a Datacenter Edition.

Hope this helps.
