Upgarde SCCM 2012 R2 SP1 to SCCM Current Branch 1610

[StewieHendrix]

Hi,

 

My appologies if I post this in the wrong forum.
Also, appologies for the very long post.

 

Our environment:

SCCM 2012 R2 SP1

One Primary Site server (no secondary sites)

Site version: 5.00.8239.1000

SQL is on the same server (SQL 2012)

Server version: Windows Server 2012 R2

11 Distribution Points worldwide

MDT: 2013 Update 2 (6.3.8330.1000)

Windows 10 ADK: 10.1.10586.0

I am new in the company and I have inherited an SCCM 2012 R2 SP1 server.

I am not an SCCM expert at all. I am still learning.

However, they are requesting to upgrade the SCCM server the latest version.

I want to make sure that everything will work after the upgrade. Hence the questions.

Currently, we are deploying Windows 10 build 1511. (as well as Win 7 and 8.1 in some cases)

We want to deploy Windows 10 1607 after the upgrade (and Win 7 and 8.1 on some devices)

 

1) Do I have to upgarde ADK to version 1607 (10.1.14393.0)?

If yes, before or after the uprade of ConfigMgr?

I remember a while ago there was a problem with a certain version of ADK 1511 and we had to skip that version.
I suppose the latest version is working fine?

 

 

2) Do I have to update MDT?

If yes, before or after the upgrade of ConfigMgr?

 

3) I did a lot of research. So I can now first upgrade to the latest baseline version 1606 and then do an in-place upgrade to 1610?

Please correct me if I'm wrong.

Also, can I do the upgrade to 1610 immediately or will I have to do/test something before proceding?

 

4) How about the update of ConfigMgr clients on our devices?

At the moment, automatic update is turned on: "Upgrade client automatically when new client updates are available".

Should I turn this off before I start with the Site upgrade to avoid automatic client updates in case something goes wrong and I have to restore backup?

5) Does anybody know of a good backup and restore guide for CM?

I want to create a backup first and be able to restore it if anything goes wrong.

As the server is on VMWare, can I take turn off the server, take a snapshot, upgrade. And if something goes wrong I restore the snapshot?

Is that sufficient?

Thank you

Anyone?
