Before you begin a site installation, it's a good idea to learn about the prerequisites for installing the different types of System Center Configuration Manager sites.
Primary sites and the central administration site
The following prerequisites apply to installing a central administration site as the first site of a hierarchy, installing a stand-alone primary site, or installing a child primary site. If you are installing a central administration site as part of a hierarchy expansion, see Expanding a stand-alone primary site in this topic.
Prerequisites for installing a primary site or a central administration site
The user account that installs the site must have the following rights:
- Administrator on the site server computer
- Administrator on each computer that will host the site database or an instance of the SMS Provider for the site
Sysadmin on the instance of SQL Server that hosts the site database
When Setup finishes, both the user account that runs Setup and the site server computer account must retain sysadmin rights to SQL Server. Do not remove the sysadmin rights from these accounts.
If you are installing a primary site, you need the following additional rights:
- Administrator on additional computers where you will install the initial management point and distribution point, if not on the site server
If you are installing a new child primary site below a central administration site, you need the following additional rights:
Administrator on the computer that hosts the central administration site
Role-based administration rights within Configuration Manager that are equivalent to the security role of Infrastructure Administrator or Full Administrator
You must use the correct installation media (source files), and run Setup from that location. For information about the correct source files to use to install different types of sites, see Options for installing different types of sites in the Prepare to install sites topic.
The site server computer must have access to updated Setup files from Microsoft, in one of these ways:
- Before you start the install, you can download and store a copy of these files on your local network by using Setup Downloader.
- If a local copy of these file is not available, the site server must have Internet access so it can download these files from Microsoft during the installation.
Before you can expand a stand-alone primary site that has a service connection point site system role installed, you must uninstall the service connection point. Only one instance of this role is permitted in a hierarchy, and it is only permitted at the top-tier site of the hierarchy. You will have the opportunity to reinstall the role during the installation of the central administration site.
- The site server and site database computers must meet all prerequisite configurations. Before starting Setup, you can manually run Prerequisite Checker to identify and fix problems.
Prerequisites to expand a stand-alone primary site
A stand-alone primary site must meet the following prerequisites before you can expand it into a hierarchy with a central administration site:
You must install the new central administration site installation using media from a CD.Latest folder (which contains the source files) that matches the version of the stand-alone primary site
To ensure a version match, use the source files found in the CD.Latest folder on the stand-alone primary site.
The stand-alone primary site cannot be configured to migrate data from another Configuration Manager hierarchy
You must stop active migration to the stand-alone primary site from other Configuration Manager hierarchies and remove all configurations for migration. This includes migration jobs that have not completed, data gathering, and the configuration of the active source hierarchy.
This is necessary because migration operations are performed by the top-tier site of the hierarchy, and the configurations for migration do not transfer to the central administration site when you expand a stand-alone primary site.
After you expand the stand-alone primary site, if you reconfigure migration at the primary site, the central administration site performs the migration-related operations. For more information about how to configure migration, see Configure source hierarchies and source sites for migration to System Center Configuration Manager.
The computer account of the computer that will host the new central administration site must be a member of the Administrator user group on the standa-lone primary site
To successfully expand the stand-alone primary site, the computer account of the new central administration site must have Administrator rights on the stand-alone primary site. This is required only during site expansion. The account can be removed from the user group on the primary site when site expansion is finished.
The user account that runs Setup to install the new central administration site must have role-based administration rights at the stand-alone primary site
To install a central administration site as part of a site expansion, the user account that runs Setup to install the central administration site must be defined in role-based administration at the stand-alone primary site as either a Full Administrator or an Infrastructure Administrator.
You must uninstall the following site system roles from the stand-alone primary site before you can expand the site:
- Asset Intelligence sync point
- Endpoint Protection point
- Service connection point
These site system roles are supported only at the top-tier site of the hierarchy. Therefore, you must uninstall these site system roles before you expand the stand-alone primary site. After you expand the site, you can reinstall these site system roles at the central administration site.
All other site system roles can remain installed at the primary site.
The port for the SQL Server Service Broker (SSB) between the stand-alone primary site and the computer that will install the central administration site must be open
To successfully replicate data between a central administration site and a primary site, Configuration Manager requires an open port between the two sites for SSB to use. When you install a central administration site and expand a stand-alone primary site, the prerequisite check does not verify that the port you specify for the SSB is open on the primary site.
Known issues when you have configured Azure services:
When you use one of the following Azure services with Configuration Manager, and plan to expand a site, after expanding the site you must remove and then recreate the connection to that service.
Use the following steps to resolve this issue:
- In the Configuration Manager console, delete the Azure service from the Azure services node.
- In the Azure portal, delete the Tenant that is associated with the service from the Azure Active Directory Tenants node. This also deletes the Azure AD web app that is associated with the service.
- Reconfigure the connection to the Azure service for use with Configuration Manager.
The following are prerequisites for installing secondary sites:
- The administrator who configures the installation of the secondary site in the Configuration Manager console must have role-based administration rights that are equivalent to the security role of Infrastructure Administrator or Full Administrator.
- The computer account of the parent primary site must be an Administrator on the secondary site server computer.
When the secondary site uses a previously installed instance of SQL Server to host the secondary site database:
The computer account of the parent primary site must have sysadmin rights on the instance of SQL Server on the secondary site server computer.
The Local System account of the secondary site server computer must have sysadmin rights on the instance of SQL Server on the secondary site server computer.
When Setup finishes, both accounts must retain sysadmin rights to SQL Server. Do not remove the sysadmin rights from these accounts.
The secondary site server computer must meet all prerequisite configurations, which includes SQL Server and the default site system roles of the management point and distribution point.
