Hi,

I need to install 1-CAS, 3-Primary Site servers, 4-Secondary Site servers in my enviornment. The version which I have to install is SCCM 2012 R2 SP1 

Intially in CAS, I have installed SCCM 2012 R2 and then installed SCCM 2012 SP2 and upgraded CAS site to SCCM 2012 R2 SP1. When I tried to add a Child Primary Site by 

installing SCCM 2012 R2, pre-requiste checker failed stating "Version mismatch" and I am unable to add child Primary site in the hierarcy

ASK:

Inorder to Upgrade SCCM 2012 R2 to SCCM 2012 R2 SP1 in CAS, Primary and Secondaries:

1) Should I install SCCM 2012 R2 first in CAS
2) Then add Child Primary site server in all the locations. While installing Primary site should I use SCCM 2012 R2 bits or directly install SCCM 2012 SP2?
3) Once all Primary site servers are setup and configured, then go ahead and run the setup of SCCM 2012 SP2 in CAS which will upgrade the environment to SCCM 2012 R2 SP1.
4) Once its done in CAS, then upgrade all Primary servers

Is this is procedure I should follow to have SCCM 2012 R2 SP1 in multi-tiered architecture?

Please confirm on the above and let me know the exact way to have SCCM 2012 R2 SP1 installed 

Thanks & Regards

Are you just setting this up? Why do you need a CAS?

Hi,

Its a business requirement to have multi-tiered architecture with CAS 

Please let me know the best possible approach to have SCCM 2012 R2 SP1 installed in the multi-architecture

Its a business requirement to have multi-tiered architecture with CAS 

Why is it required? How many clients will be managed in total?

Total no of clients all around the globe is 30K

The proposed design has already been reviewed and finalized. I am looking for a solution on this

This is a bad design and is begging for trouble!

It is unclear to me, are you just building this now or ware you trying to upgrade an existing environment?

It's never a business requirement to install a CAS unless you have over 150K clients when using R2 SP1.

Hi,

I know all about the need for CAS and its requirement. I have  mentioned business requirement since we need to route all the network traffic from my customer's regional HUB sites and hence this design was finalized 

To answer your ask, I am going to build multi-tier architecture for SCCM now

Thanks & Regards

The network traffic will not be solved by using a CAS. All Administration will need to be done at the CAS, other wise you are begging for trouble.

If you are creating this as a new site then build your CAS using CM12R2SP1. Then build each Primary site and Secondary site (via push install). Use the same media for all of them.

Check out this article https://technet.microsoft.com/en-us/jj822981.aspx 

1) You should install SCCM 2012 SP2 on all sites

2) You should then run the setup for SCCM 2012 R2 SP1 only on the top level site, in this case, the CAS

The way it works, is when you have the bits for SP2, it has all the goodies and new features. Running the R2 SP1 setup simply enables the R2 features across your hierarchy for customers who have software assurance and are entitled

Hi John,

Initially while exploring SCCM R2 SP1 upgrade, In a test environment have installed SCCM 2012 SP2 as a StandAlone Primary site server and when tried installing SCCM R2 SP1 (installable bits which is less than 5 MB), though I ran the setup using administrator privilege, the installation didn't proceed and got a prompt that "You must have local administrator permissions to install this software"

Since I was stuck with the above approach, tried with SCCM 2012 R2 and then installed SCCM 2012 SP2 to bring it to SCCM 2012 R2 SP1

Thanks for your response and sharing the link which is very useful to me. So once after installing SCCM 2012 SP2 on all sites (CAS, Primary, Secondary) then I have to run SCCM R2 SP1 only in CAS and won't get message as "You must have local administrator permissions to install this software"

Let me know my understanding is correct

Again Thanks for your valuable inputs

Sorry I should have mentioned this is a very common issue but the solution is pretty simple. Run an administrative command prompt and then type in the full path to and including Splash.hta for the R2 SP1 upgrade piece. Should run no problem that way

Hi John,

Thanks for the clarification

Will try the same way and update the thread if need any other details

Krishna

Great, let me know if it works for you
