This article details the system requirements for System Center 2025 - Service Manager (SM).

Note

Unlike the earlier releases, for SM 2025, Analysis Management Object is removed.

Software requirements

Component	Requirement
Service Manager management server	The management server needs: ADO.NET Data Services Update for .NET Framework 3.5 SP1 for Windows Server; SQL Server Native client The management server must be installed on a 64-bit edition of Windows.
Data warehouse management server	The warehouse management server requires: SQL Server Native client The data warehouse management server must be installed on a 64-bit edition of Windows.
Service Manager/data warehouse databases	The Service Manager or data warehouse databases require: SQL Server Reporting Services (SSRS). The SQL Server and Analysis Services collation settings must be the same for the computers hosting the Service Manager database, data warehouse database, analysis services database, and Reporting Services database.
Service Manager console	The console requires: Microsoft Excel in order to view OLAP data cubes on the console computer; ADO.NET Data Services Update for .NET Framework 3.5 SP1 for Windows Server. The console can be installed on 64-bit edition of Windows.
Self-Service portal	The Self-Service Portal server requires: Windows 2016 server or later; the IIS role and ASP.NET 4.5 enabled. Join the server machine to the same domain where the Service Manager SDK Service is running. Ideally, on the primary or secondary server.
Machines using self-service	The Self Service portal needs a screen resolution above 1024 X 768. Supported browsers: Microsoft Edge 121 and later; Microsoft Internet Explorer 10 and 11; Mozilla Firefox 42 and later; Google Chrome 121 and later.
SQL Server Reporting Services	In a deployment topology where the computer hosting SSRS isn't on the same computer that hosts the data warehouse management server, you've to add Microsoft.EnterpriseManagement.Reporting.Code to the global assembly cache. Learn about the manual steps.

Additional notes

• Operations Manager - Service Manager has the capability to import alerts and configuration items from an Operations Manager environment. Read about installing both Service Manager and Operations Manager in the same environment. You can create a data mart for Operations Manager.

• Configuration Manager - Service Manager can import configuration items from a Configuration Manager environment.

• Network requirements - To view external content from within knowledge articles, computers that host the Service Manager console must have Internet access, either directly or through a proxy server.

• SMTP server- You must have access to a Simple Mail Transfer Protocol (SMTP) server to use the Notification feature and for incident creation through email.

• Windows safe mode- Service Manager doesn't operate and the services used by Service Manager don't start if Windows Server is running in safe mode. If you attempt to start the Service Manager services manually while in safe mode, the services fail to start and an error is written into the event log.

SQL Server requirements

Microsoft SQL Server hosts the databases that System Center - Service Manager creates. In addition, System Center 2025 - Service Manager requires SQL Server Analysis Services (SSAS) to work with Microsoft Online Analytical Processing (OLAP) cubes. SQL Server Reporting Services (SSRS) is required to support System Center 2025 - Service Manager reporting.

Use this information to evaluate if your SQL Server environment is ready to support the installation of or upgrade to System Center 2025. Use this information whether you're deploying one or multiple components of System Center.

Note

During installation, select SQL Server full-text search on the computers running SQL Server that will host the Service Manager and data warehouse databases.

SQL Server version support

Note

• SM doesn’t support SSAS mode Tabular. Select the SSAS mode as Multi-dimensional during the installation of SQL Server.
• For the supported versions of SQL, use the service packs that are currently in support by Microsoft.
• Service Manager 2025 supports SQL 2019 with CU8 or later; however, it doesn't support SQL 2019 RTM.
• With SQL 2019 (CU8 or later), use ODBC 17.3 to 17.10.6, and MSOLEDBSQL 18.2 to 18.7.2.

Service Manager	•	•
Data Warehouse database	•	•

Note

System Center 2025 - Service Manager doesn't support the MultiSubnetFailover parameter. This parameter isn't used in System Center 2025 - Service Manager connection strings.

Allow updates

To either install or upgrade to System Center 2025 - Service Manager, computers running SQL Server that host databases must be configured to allow updates. If updates aren't allowed, System Center 2025 - Service Manager Setup won't complete and the following error message appears at the Create database stage of the installation:

An error occurred while executing a customer action: _ExecuteSqlScripts. This upgrade attempt has failed before permanent modifications were made. Upgrade has successfully rolled back to the original state of the system. Once the corrections are made, you can retry the upgrade for this role.

You can check the status of allow updates on SQL Server by executing the following stored procedure from within SQL Server Management Studio:

sp_configure 'allow updates'

In the results table, examine the value for run_value. If the value of run value is 1, set it back to 0 with the following stored procedure, and then run Setup again.

sp_configure 'allow updates',0 reconfigure with override

AlwaysOn Availability Groups considerations for Service Manager databases

SQL Server AlwaysOn Availability Groups functionality is supported by System Center 2025 - Service Manager.

For more information about installing Service Manager with AlwaysOn availability groups, refer here.

Upgrade to SQL 2019

The following steps provide information about upgrading to SQL 2019.

Note

• You must use Cumulative Update 8 (CU8) or later with SQL 2019.
• Use ODBC 17.3 to 17.10.4.1, and MSOLEDBSQL 18.2 to 18.6.6.
• Upgrade process to SQL 2019 uninstalls the reporting services; ensure to migrate required reports such as backup reporting DB and encryption keys.

Use the following steps to upgrade from SQL 2017 to 2019:

1. Upgrade to SQL 2019.
2. Install SQL 2019 reporting services (SSRS), launch the reporting services configuration manager to use the existing reporting DB, and restore encryption keys. Configure the Web service URL and Web portal URL.
3. Use the same values for reporting server Web service virtual directory and Web portal URL that you had before initiating the upgrade process for SQL 2019.
4. Configure the SSRS as per the details shared here.
5. [Optional] To enable CLR strict security, run the following script on each of the Service Manager databases. By default, CLR strict security is disabled after you upgrade to SQL 2019.

Upgrade to SQL 2022

The following steps provide information about upgrading to SQL 2022.

Note

• You must use Cumulative Update 8 (CU8) or later with SQL 2022.
• Use ODBC 17.3 to 17.10.4.1, and MSOLEDBSQL 18.2 to 18.6.6.
• Upgrade process to SQL 2022 uninstalls the reporting services; ensure to migrate required reports such as backup reporting DB and encryption keys.

Use the following steps to upgrade from SQL 2019 to 2022:

1. Upgrade to SQL 2022.
2. Install SQL 2022 reporting services (SSRS), launch the reporting services configuration manager to use the existing reporting DB, and restore encryption keys. Configure the Web service URL and Web portal URL.
3. Use the same values for reporting server Web service virtual directory and Web portal URL that you had before initiating the upgrade process for SQL 2022.
4. Configure the SSRS as per the details shared here.
5. [Optional] To enable CLR strict security, run the following script on each of the Service Manager databases. By default, CLR strict security is disabled after you upgrade to SQL 2022.

Enable CLR strict security

Optional. Use the following script to enable CLR strict security.
