In place Upgrade from Windows Server 2008 R2 standard to enterprise

I installed 40 GB of RAM on this server and installed WS 2008 R2 Standard edition. To my surprise the amount of memory it says is "40 GB (32 GB usable)". The reason it says 32 GB usable is because Standard edition only supports a max of 32 GB!

I thought i was going to have to completely reinstall to get Enterprise installed. Fortunately i found this blog post:

You can do an inplace upgrade with one command: dism  /online /set-edition: ServerEnterprise /ProductKey:xxxx
