Move from enterprise to datacenter

[imunro01]

I have a server which was installed as Enterprise, however I've now purchased a datacenter license for it. Is there an easy way to upgrade the installation without a re-install?

You can't use the datacenter key on standard as such, but you can do an inplace upgrade. Requires restarts and things, I have done it to 3 servers here with no problem:

 

 

To do this you just need to use the DSIM tool which is included with Windows

Dism /online /Set-Edition:ServerEnterprise /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

 

Note that you can check which versions you can upgrade to by running: Dism /online /Get-TargetEditions

 

 

Note that for KMS client product keys (ie ones that you can use to ensure they contact the KMS server for activation) see this article.Note this is useful for upgrading clients from Standard to Datacenter

Example

 

The below example works for our servers. Remember that the command requires a restart and takes around 10 mins.

dism /online /Set-Edition:ServerDatacenter /ProductKey:xxxxxxxxx
