In this post we will see how to uninstall SCCM primary site. Sometimes you want to try new things because you want to learn something out of it. I would like to post a quote made by Walt Disney here. “We keep moving forward, opening new doors, and doing new things, because we’re curious and curiosity keeps leading us down new paths”.

The first question you would probably ask is why should one uninstall SCCM primary site ?. There could be a situation where you would want to setup new site completely. Or probably get rid of the old primary site that has got tons of issues or it could be something else. Well I have got a big lab setup with just a single SCCM primary site. Now that I wanted to create a new setup, i thought of deleting all the virtual machines. But then, that would be so easy to do. So i thought why not try out uninstall configuration manager site option.

Long back I published a post on performing SCCM site reset. Note that SCCM site reset is different from uninstalling your configuration manager site. Though both options are seen on same screen, however one should use them wisely. If you are looking to perform SCCM Configuration manager site reset, this post will help you. In this post I will cover the steps to uninstall SCCM primary site.

Before you Uninstall SCCM Primary Site

Since you have decided to uninstall SCCM primary site, there are few things that i would like to add here. What if you have a hierarchy with multiple sites ?. Will you decommission primary site server directly ?. The answer is No. In such cases the sequence of removal is important. Remember that if your hierarchy has multiple sites, you must start by uninstalling the sites at the bottom of the hierarchy and then move upward.
