Upgrade on-premises infrastructure that supports Configuration Manager

Applies to: Configuration Manager (current branch)

Use the information in this article to help you upgrade the server infrastructure that runs Configuration Manager.

Upgrade the OS of site systems

Configuration Manager supports the in-place upgrade of the server OS that hosts a site server and any site system role, in the following situations:

  • If Configuration Manager still supports the resulting service pack level of Windows, it supports in-place upgrade to a later Windows Server service pack.

  • In-place upgrade from:

    • Windows Server 2019 to Windows Server 2022

    • Windows Server 2016 to Windows Server 2022

    • Windows Server 2016 to Windows Server 2019

    • Windows Server 2012 R2 to Windows Server 2019

    • Windows Server 2012 R2 to Windows Server 2016

    • Windows Server 2012 to Windows Server 2016

To upgrade a server, use the upgrade procedures provided by the OS you're upgrading to. See the following articles:

Upgrade to Windows Server 2016, 2019, or 2022

Use the steps in this section for any of the following upgrade scenarios:

  • Upgrade either Windows Server 2016 or Windows Server 2019 to Windows Server 2022

  • Upgrade either Windows Server 2012 R2 or Windows Server 2016 to Windows Server 2019

  • Upgrade either Windows Server 2012 or Windows Server 2012 R2 to Windows Server 2016

Before upgrade

  • (Windows Server 2012 or Windows Server 2012 R2 only): Remove the System Center Endpoint Protection (SCEP) client. Windows Server now has Windows Defender built in, which replaces the SCEP client. The presence of the SCEP client can prevent an upgrade to Windows Server.

  • (Windows Server 2012 or Windows Server 2012 R2 only): Install the latest Cumulative Update and uninstall Windows Management Framework 5.1 before attempting the upgrade.

  • Remove the WSUS role from the server if it's installed. You may keep the SUSDB and reattach it once WSUS is reinstalled. This includes removing and reinstalling the WSUS Administrative Tools on the CAS or Primary Site Server if the Software Update Point (SUP) is remote.

  • If you're upgrading the OS of the site server, make sure file-based replication is healthy for the site. Check all inboxes for a backlog on both sending and receiving sites. If there are lots of stuck or pending replication jobs, wait until they clear out.

    • On the sending site, review sender.log.
    • On the receiving site, review despooler log.

After upgrade

  • Make sure Windows Defender is enabled, set for automatic start, and running.

  • Make sure the following Configuration Manager services are running:

    • SMS_EXECUTIVE

    • SMS_SITE_COMPONENT_MANAGER

  • Make sure the Windows Process Activation and WWW/W3svc services are enabled and set for automatic start. The upgrade process disables these services, so make sure they're running for the following site system roles:

    • Site server

    • Management point

  • Make sure each server that hosts a site system role continues to meet all prerequisites. For example, you might need to reinstall BITS, WSUS, or configure specific settings for IIS.

  • After restoring any missing prerequisites, restart the server one more time to make sure services are started and operational.

  • If you're upgrading the primary site server, then run a site reset.

Known issue for remote Configuration Manager consoles

After you upgrade the site server, or an instance of the SMS Provider, you can't connect with the Configuration Manager console. To work around this problem, manually restore permissions for the SMS Admins group in WMI. Permissions must be set on the site server, and on each remote server that hosts an instance of the SMS Provider:

  1. On the applicable servers, open the Microsoft Management Console (MMC) and add the snap-in for WMI Control, and then select Local computer.

  2. In the MMC, open the Properties of WMI Control (Local) and select the Security tab.

  3. Expand the tree below Root, select the SMS node, and then choose Security. Make sure the SMS Admins group has the following permissions:

    • Enable Account

    • Remote Enable

  4. On the Security tab below the SMS node, select the site_<sitecode> node, and then choose Security. Make sure the SMS Admins group has the following permissions:

    • Execute Methods

    • Provider Write

    • Enable Account

    • Remote Enable

  5. Save the permissions to restore access for the Configuration Manager console.

Known issue for remote site systems

After you upgrade a server that hosts a site system role, the value Software\Microsoft\SMS may be missing from the following registry key: HKLM\SYSTEM\CurrentControlSet\Control\SecurePipeServers\Winreg\AllowedPaths

If this value is missing after you upgrade Windows on the server, manually add it. Otherwise site system roles can have issues uploading files to the site server inboxes.

Upgrade the OS of clients

Configuration Manager supports an in-place upgrade of the OS for Configuration Manager clients in the following situations:

  • If Configuration Manager supports the resulting service pack level, it supports in-place upgrade to a later Windows service pack.

  • In-place upgrade of Windows from a supported version to Windows 10 or later. For more information, see Upgrade Windows to the latest version.

  • Build-to-build servicing upgrades of Windows 10 or later. For more information, see Manage Windows as a service.

Upgrade SQL Server

Configuration Manager supports an in-place upgrade of SQL Server on the site database server.

For information about the versions of SQL Server that Configuration Manager supports, see Support for SQL Server versions.

Upgrade the service pack version of SQL Server

If Configuration Manager still supports the resulting SQL Server service pack level, it supports the in-place upgrade of SQL Server to a later service pack.

When you have more than one Configuration Manager site in a hierarchy, each site can run a different service pack version of SQL Server. There's no limitation to the order in which sites upgrade the service pack version of SQL Server.

Important

If you use BitLocker management in Configuration Manager, and you encrypt recovery data in the database, before you upgrade SQL Server, make sure the certificate is for a supported version. For example, certificates created with SQL Server 2014 or earlier aren't compatible with SQL Server 2016 or later. For more information, see Manage the encryption certificate on SQL Server upgrade.

Upgrade to a new version of SQL Server

Configuration Manager supports the in-place upgrade of SQL Server to the following versions:

  • SQL Server 2022
  • SQL Server 2019
  • SQL Server 2017
  • SQL Server 2016
  • SQL Server 2014

This support includes the upgrade of SQL Server Express to a newer version of SQL Server Express at secondary sites.

When you upgrade the version of SQL Server that hosts the site database, you must upgrade the SQL Server version that's used at sites in the following order:

  1. Upgrade SQL Server at the central administration site first

  2. Upgrade secondary sites before you upgrade a secondary site's parent primary site

  3. Upgrade parent primary sites last. These sites include both child primary sites that report to a central administration site, and stand-alone primary sites that are the top-level site of a hierarchy.

When you upgrade a site database from an earlier version of SQL Server, the database keeps its existing cardinality estimation level, if it's at the minimum allowed for that instance of SQL Server. If you upgrade SQL Server with a database at a compatibility level lower than the allowed level, it automatically sets the database to the lowest compatibility level allowed by SQL Server. For more information, see Supported SQL Server versions: Database compatibility level.

For more information about upgrading SQL Server, see the following SQL Server articles:

To upgrade SQL Server on the site database server

  1. Stop all Configuration Manager services at the site

  2. Upgrade SQL Server to a supported version

  3. Restart the Configuration Manager services

Note

When you change the SQL Server edition in use at the central administration site from Standard to either a Datacenter or Enterprise, the database partition doesn't change. This database partition limits the number of clients the hierarchy supports.
