# Overview

This guide provides insights on what to expect when CME MP and RC operate side by side in the same org independently, without interoperating. It covers design-time configuration, including setup, metadata, and data model, and run time behavior, including user flows, automation, and UI.

### Required Editions

<table class="slds-table slds-table_bordered slds-max-medium-table_stacked slds-m-bottom_small edition"><colgroup><col></colgroup><tbody><tr class=""><td class="slds-cell-wrap" style="vertical-align:top;">Available in: Classic and Lightning Experience</td></tr><tr class=""><td class="slds-cell-wrap" style="vertical-align:top;">Available in: <strong>Enterprise</strong>, <strong>Unlimited</strong>, and <strong>Developer</strong> Edition</td></tr></tbody></table>

There are two types of operating models that can be in use. Both of them have different implications.

Separate users setup: Assign Distinct CME MP only and RC only users on the app (CME MP or RC) via profile or permission set. How the boundary is enforced: Permissions enforce the boundary so that a user only reaches their app (CME MP or RC) surfaces. Strongest isolation.

Common or Shared user setup: One identity carries both apps (CME MP and RC). How the boundary is enforced: Permissions can’t enforce the boundary as it relies on app (CME MP or RC) such as scoped surfaces, the record differentiator, and validation rules. The differentiator does the heavy lifting.

Note We plan to verify more co-existence scenarios in subsequent releases, beyond the initial set covered in the Winter '27 release. We’re yet to scope, MACD scenarios, and ESM [Enterprise Sales Management (Managed Package)](https://help.salesforce.com/s/articleView?id=ind.comms_t_enterprise_sales_management_overview_55069.htm&language=en_US) or any other items that aren’t delivered as a part of Winter ‘27.
