Hello All.
We are planning to upgrade our existing Cognos 10.2.2 to CA. Instead of going big bang, we wanted to go in a phased approach,starting with our Dev environment first. Also, looking at the consumption and usage patterns, our Dev & Test environments are used only by the Developer community hence they are not over loaded.
My plan is to decommission couple of dispatchers from Cognos 10 Dev & Test environment and make them Cognos 11 dispatchers while Cognos 11 shares the Cognos 10 content store.
In my view, we can have a new environment that can be used by LCM and eventually moving to Cognos 11.
Please let me know if this is a viable approach or do you see any potential risks that I may encounter.
Appreciate any inputs !!
Thanks & Regards
Raj

Cognos 11 must have its own content store. They cannot share a content store.
As for your environment, as long as everything is running on different ports and the infrastructure can handle the load, I don't see any issues.

Is there a reason why its not compatible. Logically, I presume it would be a new set of system tables for CA within the same database.Even if I have to go with a new Content Store, can I backup and restore of old Cognos 10 CS to get my user roles & groups or should I have to go with Deployment (export & import wizard) in this case.
Thanks & Regards

Sorry Raj, I misunderstood :). When you said "share the same content store", I thought you meant share the same set of DB tables. Of course you could have more than one content store database in the same environment.

Sorry for the confusion Jay, I should have perhaps phrased it correctly :). Yeah, I meant new set of CA tables within the same database.
Thanks again for your inputs

Raj,
This approach would work as long as you follow the points discussed by CognoidJay (New CM, Different Ports, etc.).
One thing i would be wary of is the dependency on LCM! We have recently gone from Cognos 10.2 to 11R5 and were unable to validate any report runs, outputs, etc.
I bring this up as part of your project plan you may need to allow more time for regression testing.

Thanks Adam for your inputs, will make a note of it. Btw, was that a multi version co-existence with different versions of cognos and is it still supported with Cognos 10.2.2 and CA?

In a distributed environment with 3 Servers to evaluate CA 11 what would be the optimal way for configuring different components on these three server
Server 1 (Webserver + Dispatcher)
Server 2 (Dispatcher + Content Manager)
Server 3 (Dispatcher + Backup Content Manager)
Vs
Server 1 (Webserver + Content Manager)
Server 2 (Dispatcher)
Server 3 (Dispatcher+Backup Content Manager)
My preference would be having a dedicated Server for Content Manager.However, with the limited resources that I have in hand I'm confined to use three server. I'm look a combination that would minimize the risk during a failure.
Appreciate your thoughts and inputs.

Hello All,
Looking at a better risk mitigation strategy in the event of a system failure, my view is to have something like -
Server 1 (Webserver+Dispatcher)
Server 2 (Content Manager)
Server 3 (Dispatcher+Backup Content Manager)
This way I can have a dedicated Content Manager and I dont have to change anything, if I have to scale-up my environment I can just install the Application Tier (dispatchers) in future.
Appreciate expert thoughts and inputs.
Thanks & Regards
Raj.
