SCCM 1706 Upgrade Guide – Updates and Servicing

3

Microsoft SCCM team released the production version of SCCM 1706. The SCCM 1706 updates are available as an in-console update for previously installed sites that run version SCCM CB versions 1606, 1610, or 1702.

In this post, we see the SCCM 1706 in place upgrade video tutorial and the secret behind the success of SCCM CB Updates and Servicing. More details about SCCM CB 1706 new features are documented here.

The SCCM 1706 upgrade step by step video guide here. This provides more details about the replication, pre-requisite checks, actual upgrade process of SCCM CB 1702 to 1706 and how to enable pre released Features, etc..

Also, I have another post “Feature Comparison Video SCCM ConfigMgr CB 1702 VS 1706” – here (published later in this week).

What is the Secret of SCCM Updates and Servicing Model?

The real secret is nothing but continuous improvements which Microsoft SCCM PG (Product Group) put in SCCM CB. There are loads of things involved in continuous improvement story. In this post, we are going to see one part of it and that is prerequisite checks during in console update and servicing process.

I think SCCM PG works based on feedback and telemetry data to improve prerequisite checks.

SCCM 1706 Secret Behind the Success of SCCM CB Updates and Servicing

Why is the Prerequisite checks are important in Updates & Servicing Model?

The prerequisite checks are one of the important piece in SCCM CB updates and servicing framework. Do you know how many prerequisite checks are there in this frame work? SCCM CB updates and serving prerequisite checker validates the entire SCCM CB infra whether it’s ready for in place upgrade. Hence it can make sure 99% the upgrade will be successful.

There are 62 prerequisite checks in the release of SCCM CB 1706. I never knew that SCCM CB upgrade process goes through 62 checks. This is to make sure that everything OK to start the upgrade.

I have listed down all the checks included in the production version of SCCM CB 1706. The prerequisite checks cover CAS, Primary servers, remote site systems servers.

It also includes SQL version, Collation settings and Replication link verification. SCCM CB prerequisite checks consist of unsupported configurations (NAP, System Health Validation Point) with SCCM CB environment.

  1. Dear Anoop,
    no doubt, there is improvement in the product.
    However, personally I would not assume that the Upgrade and Servicing module is already error-free. Depending on the individual environment, it might just stop during the upgrade process, which is exactly the opposite of what this feature is for.
    So all in all I think there is still room for improvement.
    Excuse me if you intended to bring this already over in your article, I just wanted to point out another critical aspect of the entire product.
    Usually we perform such related update steps during the weekend, thus making it more of a hassle if something goes wrong 😉

    • Yes, there is still room for improvement. I totally agree and as community we need to provide the feedback to the product group via User Voice requests. And the important point is like few years before “we don’t need to wait another couple or 3 years for this improvement to happen in the product”. Nowadays improvements are happening every couple of months or at least every 4 months. This is great stuff
