How to Expand SCCM CB Standalone Primary server with CAS server Configuration Manager ConfigMgr? In this post, we will see how to expand the stand-alone primary server and attach it to CAS.
We need to install an SCCM CB CAS server from the latest source files, we can get the latest source files from the stand-alone primary server’s CD.Latest folder.
Here are more details about CD. The latest folder in my previous blog is here. When do you want to convert/expand your SCCM CB stand-alone primary server to a hierarchy and install SCCM CB CAS?

More Details – How to Expand SCCM CB Standalone Primary Server with CAS Server
I’ve created a video tutorial to explain the process of expanding the SCCM CB stand-alone primary server. Before starting the expansion activity, we need to consider some essential prerequisites.
- We must install the new SCCM CB CAS server from the installation media (source files) –CD.Latest Folder- that matches the version of the stand-alone SCCM CB primary site.
- The SCCM CB stand-alone primary site cannot be configured to migrate data from another SCCM hierarchy. Remove all those migration configurations before expansion.
- The SCCM CB CAS server’s computer account must be a member of the Administrators group on the stand-alone primary site. You may or may not remove this account after the expansion.
- The user account that runs setup to install the SCCM CB CAS server must have FULL Admin or Infra Admin permissions at the stand-alone primary site.
- Before you can expand the site, we have to uninstall the following site system roles from the SCCM CB stand-alone primary site: the Asset Intelligence synchronization point, the Endpoint Protection point, and the Service connection point.
- The SQL Server Service Broker(4022) port must be open between SCCM CB CAS and a stand-alone primary server.
