Which of the following systems is provided to you only via the SUM tool in a system conversion?

The SAP S/4HANA Cloud Private Edition is provided exclusively through the Software Update Manager (SUM) tool during a system conversion. This is significant because SUM is the primary tool designed to handle the technical conversion of the existing system to SAP S/4HANA while managing the complexity of the different system landscapes and ensuring a smooth transition.

When converting to the cloud private edition, SUM offers comprehensive functionalities including the migration of data, adjustments to system configurations, and the implementation of necessary updates and innovations. The SUM tool is specifically designed for on-premise and private cloud environments, which aligns with the requirements of the SAP S/4HANA Cloud Private Edition.

In contrast, other options listed like the SAP Business Technology Platform, SAP Signavio Process Collaboration Hub, and SAP Signavio Process Manager serve different roles and can be utilized in different contexts outside of the specific technical conversion process that SUM handles for the cloud private edition. These tools provide various capabilities related to application development, process management, and collaboration but do not rely solely on SUM for their implementation or provisioning.
