SCCM 2309 Infra Upgrade Important things to remember

Let’s look into the details of the SCCM 2309 Infra Upgrade and important things to remember before starting the upgrade in this post. Microsoft released the second version of SCCM in the year 2023.

There are only 2 versions of SCCM releases per year. Recently, Microsoft changed the release timing of the SCCM version to 2 Versions per Year. The release months are March and September. SCCM Technical Preview version cadence will also change from 12 releases to 4 per year.

SCCM 2309 is available as an opt-in version for Oct 2023 month. So, you need to enable the opt-in option using the PowerShell script, as discussed in the Download SCCM 2309 Early Ring Version post.

Starting with the 2309 release of SCCM, it’s crucial to have the ODBC driver for SQL Server 18.1.0 or later installed as a prerequisite. More details on the SCCM 2309 infra upgrade are given below.
