Upgrading WSUS Server

I want to get my WSUS environment ready for Windows 2012 so I was reading this article about the update.  Perhaps I'm an idiot but after reading this section on applying the update:

1. Start the process with WSUS 3.0 SP2 that synchronizes with Microsoft Update.
2. Apply this update.
3. Start a synchronization.
4. Wait for the synchronization to succeed.
5. Repeat steps 2 through 4 for each WSUS 3.0 SP2 server that synchronizes to the server that you just updated.

I was not able to find where this update is listed.  According to the article, I should be looking for KB2734608 but a search for that in my WSUS server turns up nothing.  Do I not have something selected properly in the options, perhaps under the Products and Classifications?
