Hi KH, when planning to use external CPE and external ICN , you can choose the appropriate BPMConfig properties (like externalICNCPE_ProcessCenter.properties ). During installation, this will skip creation of the internal environments.
Even if you're not starting with existing Case Manager environments, the steps described in https://www.ibm.com/support/pages/node/7156782 might still provide some idea how working with external CPE/ICN will be covered.
You may want to consider working with an experienced services consultant to get things started efficiently.
