Comprehensive SCCM 1902 Upgrade Guide

This post is a complete step-by-step SCCM 1902 upgrade guide. Microsoft released their first SCCM current branch version of the year 2019 i.e. SCCM 1902 today. You can now plan to upgrade your SCCM Current Branch environment to the latest 1902 version. The Configuration Manager 1902 is out and comes loaded with new features and improvements over SCCM 1810.

Most of all you can begin upgrading your SCCM current branch setup to version 1902. I can see lot of user voice items have also been baked in SCCM 1902. So pretty much excited to upgrade my Configuration Manager current branch to version 1902.

Configuration Manager 1902 includes lots of new features and improvements. This SCCM 1902 upgrade guide will be part of my SCCM current branch guides as well. You can download all Configuration Manager current branch guides.

SCCM 1902 Prerequisites Upgrade Checklist

Here are some of the SCCM 1902 prerequisites that you need to look into before you install SCCM 1810 update.

  • To install ConfigMgr 1902 update, you must have installed at least SCCM 1802, 1806 or SCCM 1810.
  • Ensure that you are running a supported Operating System and SQL version.
  • If you’re running a multi-tier hierarchy, start at the top-level site in the hierarchy. First perform the CAS upgrade, later you can begin the upgrade of each child site. Complete the upgrade of each site before you begin to upgrade the next site.

How to get Configuration Manager 1902 Update

We have seen in this past that every SCCM update is rolled out globally. For existing customers it might take some time to appear in the Updates and Servicing node. However you will be notified when it is ready to install from the “Updates and Servicing” node in your Configuration Manager console.

In my lab setup, I had to run a fast update ring script to quickly get the 1902 update. The PowerShell script can be downloaded by clicking this link.

Should I install SCCM 1810 Hotfixes first ?

I am sure this is one of the question that comes to mind before installing version 1902. There were several hotfixes released for SCCM 1810. Each hotfix came with certain fixes and probably you may not have installed any or installed just few hotfixes. If you are installing update 1902, then you can skip the hotfix installations. The fixes that these hotfixes contained are already included in 1902 update.

In my lab setup notice that I upgraded to Configuration Manager 1902 directly from Configuration Manager 1810. I did not install any hotfix and yet the upgrade was successful. Therefore if you have already installed all the hotfixes, you can still install update 1902.

Here are the list of SCCM 1810 Hotfixes.

SCCM 1902 Prerequisite Check

Before you do a SCCM 1902 upgrade, you must run the prerequisite check first. After running the PowerShell script, I had to restart SMSEXEC service and I could see the Configuration Manager 1902 update. Before installing the update, I ran a prerequisite check.

SCCM 1902 Prerequisite Check

Almost everything was good but I could see just one warning. Potential SQL server performance issue caused by change tracking retention period. Warning – Configuration Manager detects the site database has a backlog of SQL change tracking data. I have blogged about this warning in this post.
