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.

3Check the current edition
DISM /online /Get-CurrentEdition, check if it's upgradeableDISM /online /Get-TargetEditions, and if it isDISM /online /Set-Edition:<edition ID> /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX /AcceptEula. Two restarts latter you should be good to go. – Brian – 2014-08-07T11:57:44.520
