Microsoft has released the first SCCM version for 2024 as the release cadence is now reduced to 2 releases per year. SCCM 2403 was released on April 23rd, 2024. This post is a complete step-by-step SCCM 2403 upgrade guide, meaning that if you want to upgrade your existing SCCM installation to the latest SCCM updates, this post is for you.

If you’re looking for a comprehensive SCCM installation guide to building a new server, refer to our blog series which covers it all.

You won’t be able to install SCCM 2403 if you are running SCCM 2012. Well, that’s an odd phrase! Thank you current branch naming.

SCCM 2403 isn’t a baseline version. SCCM 2403 is a baseline version. This means that if you’re downloading the source from Volume Licensing, SCCM 2403 will be the version of your new SCCM site. Upgrading to a later version (when released) will be available after the original installation.

At the time of this writing, SCCM 2403 is available in the Early update ring. You must run the opt-in script to see it appear in the console. We’ll cover that in the Installation section.

To install SCCM 2403 as an update, you must have installed SCCM 2211 or later. If you check for updates in your console and it’s not showing up, continue reading, we’ll describe how to get it using the “Fast Ring” script.

Keeping your infrastructure up to date is essential and recommended. You will benefit from the new features and fixes, some of which can apply to your environment. It’s easier than ever to upgrade since Microsoft has implemented the servicing model directly from the console.

SCCM 2403 Upgrade Guide – New Features and Fixes

SCCM 2403 includes fewer new features and enhancements than its predecessors.

You can consult the What’s new in version 2403 of Microsoft Configuration Manager article for a full list of changes.

There are 2 important warnings that you must be aware of before upgrading to this version.

If you have HTTP-only communication enabled, you must at least enable Enhanced HTTP for client communication or HTTPS.

If your SCCM server is still running Windows 2012, you must upgrade your site server Operating system before upgrading.

Here’s our list of favourite features :

  • Automated diagnostic Dashboard for Software Update Issues
  • Folder support for Scripts node
  • Improvements to console search
  • Enhancement in Deploying Software Packages with Dynamic Variables

Support for SCCM Current Branch Versions

Ensure to apply this update before you fall into an unsupported SCCM version. Read about the support end date of the prior version of the following Microsoft Learn article. The SCCM 2403 version will be supported until October 22, 2025.

Windows and SQL Support

Before installing, make sure that you are running a supported Operating System and SQL version. Older SCCM version was giving a warning during the Prerequisite check but 2403 is giving an error that prevents the installation from continuing.

SCCM 2403 supports only Windows Server 2016+ and SQL 2014 SP3+ but recommends SQL 2016 and up.

Before you Begin – SCCM 2403 Upgrade Guide

Downloading and installing this update is done entirely from the console. There’s no download link, the update will appear on your console once the Service Connection Point is synchronized.

If you’re running a multi-tier hierarchy, start at the top-level site in the hierarchy. After the CAS upgrade, you can begin the upgrade of each child site. Complete the upgrade of each site before you begin to upgrade to the next site. Until all sites in your hierarchy are upgraded, your hierarchy operates in a mixed version mode.

Before applying this update, we strongly recommend that you go through the upgrade checklist provided on Microsoft Learn. Most importantly, initiate a site backup before you upgrade.

There are a couple of new important prerequisite checks in this SCCM 2403 release :

Configuration Manager current branch version 2403 has an error prerequisite rule that checks for Microsoft OBDC Driver 18 for SQL setup. This is needed to be installed manually prior to run the SCCM 2403 upgrade, on all site system servers.
To download the Microsoft ODBC Driver 18, click here
The installation of Microsoft ODBC Driver 18 does not require a restart.
Simply rerun the Prerequisite check after the installation.

The prerequisite check will verify all that for you :

sccm 2403 upgrade

If you migrated your site to EHTTP, you’ll have a warning about the Network Access Account that is no longer needed. See Microsoft Support Article on this subject.

[Completed with warning]:The site server configured with HTTPS/Enhanced HTTP, does not require network access account. Please verify the minimum appropriate permission of this account(s) and remove the account(s) which has higher privileges. We recommend you remove the configured network access account(s) which are not leveraged.For more information about your network access account required permissions, see

In this post, we will update a stand-alone primary site server, consoles, and clients. Before installing, check if your site is ready for the update:

  • Open the SCCM console
  • Go to Administration \ Updates and Servicing
  • In the State column, ensure that the update Configuration Manager
    2403 is Ready to install
  • If it’s not available, right-click Updates and Servicing and select Check for Updates

The SCCM 2403 update is not yet available for everyone. If you need it right away you can run the Fast-Ring script and the update will show up.

  • If the update is not downloading, click on the button Download on the upper node. The update state will change to Downloading
  • You can follow the download in Dmpdownloader.log or by going to Monitoring / Updates and Servicing Status, right-clicking your Update Name, and selecting Show Status
  • The process will first download .CAB file and will extract the file in the EasyPayload folder in your SCCM installation directory.
  • It can take up to 15 minutes to extract all files.

SCCM 2403 Upgrade Guide

Step 1 | SCCM 2403 Prerequisite Check

Before launching the update, we recommend launching the prerequisite check first. To see the prerequisite checklist, see the Microsoft Documentation

  • Open the SCCM console
  • Go to Administration \ Updates and Servicing
  • Right-click the Configuration Manager 2403 update and select Run prerequisite check
sccm 2403 upgrade
  • Nothing will happen, the prerequisite check runs in the background and all menus are unavailable during the check
  • One way to see progress is by viewing C:\ConfigMgrPrereq.log
SCCM 2207 Upgrade Guide
  • You can also monitor prerequisite checks by going to Monitoring / Update and Servicing Status, right-clicking your Update Name and selecting Show Status
  • If you have any warnings, follow the recommendation to fix the issue in the bottom pane
sccm 2403 upgrade
  • The check if HTTPS or Enhanced HTTP is enabled will probably pop for a lot of you. We release a full blog post on how to fix this warning. HTTP-only communication is deprecated, and support is removed from this version of Configuration Manager. Enable HTTPS or Enhanced HTTP for client communication.
  • When completed the State column will show Prerequisite check passed
  • Right-click the Configuration Manager 2403 update and select Install Update Pack

Step 2 | Launching the SCCM 2403 Update

We are now ready to launch the SCCM 2403 update. At this point, plan about 45 minutes to install the update.

  • On the General tab, click Next
sccm 2403 upgrade
  • On the Features tab, checkboxes on the features you want to enable during the update
sccm 2403 upgrade
  • Don’t worry, if you don’t select one of the features now and want to enable it later, you’ll be able to so by using the console Administration \ Updates and Servicing \ Features
SCCM 1902 Upgrade Guide
  • In the Client Update Options, select the desired option for your client update
sccm 2403 upgrade
  • On the License Terms tab, accept the license terms and click Next
sccm 2403 upgrade
sccm 2403 upgrade
  • On the Summary tab, review your choices, click Next and close the wizard on the Completion tab
sccm 2403 upgrade

The whole process took a minute but the installation begins on the back end.

  • During installation, the State column changes to Installing
  • We suggest you monitor the progress, by navigating to Monitoring / Updates and Servicing Status, right-clicking your Update Name and select Show Status
sccm 2403 upgrade

Unfortunately, the status is not updated in real-time. Use the Refresh button to update the view.

  • Open the SCCM update log SCCMInstallationDirectory\Logs\CMUpdate.log with CMTrace

We’ve done numerous SCCM upgrades. Some installations start a couple of minutes after you complete the wizard but we’ve seen some installation starts after a 10 minutes delay. Do not reboot or restart any services during this period or your update can be stuck in the “Prerequisite check passed” status. There are actually no officially documented methods by Microsoft to fix that. Patience is the key!

  • When completed, you’ll notice the message There are no pending update packages to be processed in the log file
  • Monitoring / Updates and Servicing Status, right-click your Update Name and select Show Status, the last step will be Installation Succeeded
  • Refresh the Updates and Servicing node in Administration, the State column will be Installed

Updating the Outdated Consoles

As a previous update, the console has an auto-update feature. At the console opening, if you are not running the latest version, you will receive a warning and the update will start automatically.

  • Since all update operations were initiated from the console, we didn’t close it during the process. We received a warning message when clicking certain objects. You will have the same message when opening a new console
  • Click OK, console restart and the update will start automatically
SCCM 1906 Upgrade Guide
SCCM 1906 Upgrade Guide
  • Wait for the process to complete. You can follow the progress in C:\ConfigMgrAdminUISetup.log and C:\ConfigMgrAdminUISetupVerbose.log. Once completed, the console will open and you’ll be running the latest version



After setup is completed, verify the build number of the console. If the console upgrade was successful, the build number will be 9128 and the version is now Version 2403.

SCCM Servers

  • Go to Administration \ Site Configuration \ Sites
  • Right-click your site and select Properties
  • Verify the Version and Build number

Upgrade SCCM 2403 Clients

The client version will be updated to 5.00.9128.100x (after updating, see the section below)

SCCM 2403 Client Package distribution

You’ll see that the 2 client packages are updated:

  • Navigate to Software Library \ Application Management \ Packages
SCCM 1906 Upgrade Guide
  • Check if the update is successful, otherwise, select both packages and initiate a Distribute Content to your distribution points

Boot Images

Boot images will automatically update during setup. See our post on upgrade consideration in a large environment to avoid this if you have multiple distribution points.

  • Go to Software Library / Operating Systems / Boot Images
  • Select your boot image and check the last Content Status date. It should match your setup date

SCCM 2403 Upgrade Guide – Upgrade Clients

Our preferred way to update our clients is by using the Client Upgrade feature: (You can refer to our complete post documenting this feature)

  • Open the SCCM Console
  • Go to Administration / Site Configuration / Sites
  • Click the Hierarchy Settings in the top ribbon
  • Select Client Upgrade tab
  • The Upgrade client automatically when the new client update is available to the checkbox is enabled
  • Review your time frame and adjust it to your needs

Reconfigure SQL Server AlwaysOn availability groups

To complete SCCM 2403 Upgrade Guide, if you use an availability group, reset the failover configuration to automatic. For more information, see SQL Server AlwaysOn for a site database.

Reconfigure any disabled maintenance tasks

If you disabled database maintenance tasks at a site before installing the update, reconfigure those tasks. Use the same settings that were in place before the update.

SCCM 2403 Upgrade Guide – Monitor SCCM Client Version Number

SCCM Reports Client Version

You can see our SCCM Client version reports to give detailed information about every client version in your environment. It’s the easiest way to track your client updates.


In conclusion, you can create a collection that targets clients without the latest client version because is very useful when it comes to monitoring a non-compliant client.

Here’s the query to achieve this: (You can also refer to our Set of Operational Collection Powershell Script which contains this collection)

select SMS_R_SYSTEM.ResourceID,SMS_R_SYSTEM.ResourceType,SMS_R_SYSTEM.Name,SMS_R_SYSTEM.SMSUniqueIdentifier,SMS_R_SYSTEM.ResourceDomainORWorkgroup,SMS_R_SYSTEM.Client from SMS_R_System where SMS_R_System.ClientVersion != '5.00.9128.1000'

Since upgrading to 2403, both our prod and lab environments are having problems with the console crashing when opening\creating packages and task sequences. Has anyone else seen this behavior? Could someone on 2403 do a quick test to see if y ou can create a new package?
