SAP CCtr upgrade - Current Version

Hi ,

We are currently running SAP CCtr and hence we need to upgrade . I have the following questions regarding the same:

1. What is the most stable SAP CCtr release as of now to which we can upgrade?

2. What are the steps for upgrade? Do we need to upgrade IA and then HAC, followed by upgrading the software packages ? Why do we need to upgrade IA ? Can we just upgrade HAC and them to the synchronization?

3. What are the pre-requisite steps for upgrade? Is there any checklist ? How can we take care of recovery in case things go wrong?

4. What are the changes in system functionality, SC or IA parameters if we upgrade from present to the level as per Ques 1

I know its a lot of questions but this upgrade will be done directly in production server and hence need to be extremely careful. Thanks!
