How convert Windows 2012R2 standard to Datacenter

There are few requirements for Datacenter as Standard now supports a lot of RAM out of the box.  The main thing that Datacenter does offer is HotPlug of RAM and CPU - useful for database servers or web servers where it is difficult to negotiate to downtime to bring down a system.
A system can be upgraded to Datacenter without losing the software configuration.  It takes about 10 - 15 minutes and it requires two reboots.
Logon to the Windows server you want to do the work on and start a command prompt with Admin privileges.
Type in:
dism /online /Get-TargetEditions
This will show you the OS you can upgrade to - it is useful just as a little check that the OS you are doing the work on will do what you are expecting it to do.
If all good, and you want to go to Datacenter then type in
dism /online /Set-Edition:ServerDatacenter /ProductKey:W3GGN-FT8W3-Y4M27-J84CP-Q3VJ9 /AcceptEula
The product key is just the KMS key that tells the server to look for a KMS server to authenticate it.  If you are working on a server in the DMZ, then you will need to use a MAK key and then use the telephone authentication system.
You can then add the extra RAM and CPU as required.  If you are doing this work on a live SQL server you will need to type in commands for the SQL process to 'see' the extra hardware resources - which will be another blog!
