As mentioned in my first blog of this year a walkthrough of the upgrade to SCCM 2012 SP1. First of all needless to say maybe, but download all the things you need. This is not only the media of SCCM 2012 SP1, but also ADK (Windows Assesment and Deployment Kit) that can be found here http://www.microsoft.com/en-us/download/details.aspx?id=30652 To make sure you are ready to start check the following pages:

Check the version of SQL you are using and check if this is supported for SP1, otherwise take care of the matter before you continue. Then install the following items from ADK:
Then, if you are upgrading in a production environment, make sure you have backups and check that your environment is healthy. When everything is ready to go start the SP1 installation. Below you will find the screenshots with remarks if needed.
As you can see below, we have the upgrade option!
Fill in your product key to continue
Accept the license terms
Download the prerequisite downloads or point to a location if you already have downloaded them.
Select Server en Client languages
The Prerequisite check will be started
If there are no real issues upgrade can start. You can follow the process by opening the log file and patiently wait till the upgrade is finished.
When you close the screen above you can open the console and check that everything is functioning properly. One of the things to double check is the SUP role, there have been reports on the internet that after upgrade the port WSUS uses has been reset and set to port 80 instead of 8530.
As you can see the upgrade is staight forward for a single site environment and certainly advisable since SP1 will give you a lot of new options. Good luck upgrading!
