SAP Rise Migration to the Swiss Private Cloud

Since 2024, T-Systems Switzerland has been offering RISE with SAP in its own Swiss private cloud. The local Future Cloud Infrastructure (FCI) enables companies to operate their SAP systems entirely within Switzerland, thereby offering an alternative to international hyperscalers. At the same time, it meets high standards for data sovereignty, security, compliance, and availability.

Together with T-Systems Switzerland, we support SAP customers in their transformation to the cloud. As part of this collaboration, we helped a major Swiss energy provider migrate its existing, complex SAP system landscape from its previous on-premises environment to the SAP RISE Private Cloud.

The existing landscape consisted of several closely interconnected SAP systems as well as numerous interfaces to internal and external systems. Accordingly, it was crucial to establish a complete picture of the existing architecture and its dependencies before the actual migration.

The goal was to securely migrate the SAP systems to the new environment and then transition them in an orderly manner to the SAP RISE operating model, hosted by T-Systems Switzerland.

The system landscape consisted of several closely integrated SAP systems. The goal was the complete migration of the SAP systems as well as their controlled operational handover to the SAP RISE operating model, hosted in the private cloud of T-Systems Switzerland.

To begin with, we worked with the client to thoroughly analyze the existing SAP landscape from the ground up. We identified all interfaces, systems, and involved partners, documented existing dependencies, and clarified technical and organizational responsibilities. In addition, we defined relevant technical and business test cases. In this way, we established a transparent foundation for the upcoming migration.
Based on this analysis, we worked with T-Systems Switzerland to develop the target architecture for the SAP RISE Private Cloud. The SAP systems were set up in the new environment, and existing connections and integrations were specifically adapted to the new infrastructure.
This included, among other things, adapting cross-system interfaces, configuring necessary network and firewall permissions, and setting up the SAP Cloud Connector and corresponding security zones. We reconfigured existing integrations between the various systems for the new environment.
Using this structured approach, we guided the client step by step on their journey to the private cloud and laid the groundwork to ensure that the complex SAP landscape would continue to operate securely, stably, and reliably even after the transformation.
