CA CSM uses CA Datacom/AD as its enterprise database repository. CA Datacom/AD is a prepackaged suite of CA Datacom components that are used internally by CA CSM and is included in the CA CSM install package. You do not have to install any version of CA Datacom separately and you would also not be able to upgrade the CA Datacom/AD version that installed as a part of CA CSM product.
I am upgrading my CA Datacom/AD from r14 to r15, can I also upgrade the CA Datacom/AD that is installed with CA CSM to r15?
No it is not possible to upgrade the CA Datacom/AD release that is installed with CA CSM. The CA Datacom/AD that comes with CA CSM cannot be used as a standalone product, it is for use exclusively by CA CSM as its enterprise database repository. Upgrading your CA Datacom/AD release will have no affect on the CA Datacom/AD installed with your CA CSM as they are completely separate datasets.
CA Datacom/MSM Version 14.0 https://docops.ca.com/ca-chorus-software-manager/6-0-1/en/version-details/enhancements-to-existing-features/ca-datacom-msm-version-14-0
I've upgrade my other CA solutions that use Datacom/AD from R14 to R15. Is CSM compatible with R15?
