Invalid License Key Error When Performing Windows Edition Upgrade

Last week, I decided to perform the in-place edition upgrade from Windows Server 2012 R2 Essentials to Windows Server 2012 R2 Standard on my home server as part of a multitude of things I’m working on at home right now. Following the TechNet article for the command to run and the impact and implications of doing the edition upgrade at http://technet.microsoft.com/en-us/library/jj247582 I ran the command as instructed in the article but I kept getting a license key error stating that my license key was not valid.
