Microsoft released new version of SCCM Current Branch version and that is SCCM CB 1610. If you are running SCCM CB 1511 or 1602 or 1606, you can directly upgrade to SCCM CB 1610. More details about SCCM ConfigMgr CB Updates in Console and Upgrade in this post and video.
SCCM Upgrade Process
The ConfigMgr CB upgrade process via updates and servicing channel is very straight forward, if you have a ONLINE service connection point mode. If you are running an offline service connection point mode then you need to perform some manual ways to get the latest version of SCCM CB 1610 updates available in your SCCM CB console.
SCCM Online Service Connection Point
For SCCM CB infra with online service connection point, the SCCM CB 1610 update will automatically appear in the console once Microsoft has released this for “slow ring“. Now (18th Nov 2016) Microsoft released SCCM CB 1610 updates only for the “fast ring” which can be enabled only through running a PowerShell script which is provided in the following link here.
SCCM Servicing Flowchart
Here is the flow chart documentation here
This is 1 minute video which tells you to how to start the SCCM CB 1610 upgrade process once the updates are available in CM CB console. I have already covered the end to end SCCM CB upgrade process in a video here (even thought that is about CM 1606 upgrade the process is similar).
Start of Upgrade process from Console
I’m sharing the video tutorial about How to Upgrade SCCM ConfigMgr CB 1610 console. You need to make sure all the reset activities of site system roles (sitecomp.log gives you more idea) have been complete before you initiate the upgrade process of SCCM ConfigMgr CB console. Otherwise there could be more chances of failures during SCCM CB console upgrade.
