CASCADE Testing and Simulation


Clearstream Banking AG, Frankfurt (CBF) offers customers a testing and simulation environment.

Customer simulation for upcoming releases and projects

Via the customer simulation environment (IMS23), CBF settlement services can be tested on customer demand. IMS23 is connected to the T2S Pre-Production environment (UTEST). This setup enables a continuous end-to-end testing for customers acting in ICP and DCP mode.

For upcoming releases, CBF offers guided customer simulation and related test cases dedicated to the enhancements developed by Clearstream. The timelines for guided simulations will be announced together with the request to register. In some functional areas, dedicated test cases will be offered by CBF to support the simulation of business cases where specific test environment requirements are necessary. The participation in the guided customer simulation is optional and not a prerequisite for admission to production for the launch date.

As part of the customer readiness, a related customer simulation is planned for the project Corporate Actions Harmonisation (CAH) - KADI DE Migration to OneClearstream Asset Servicing (OneCAS) in the second quarter of 2023.

In Announcement C23005 Clearstream Banking informed that the NextGenerationEU issuance is planned for Q3 2023.

In the period 3 to 16 May 2023, customers can participate in a testing. Clearstream Banking’s format description for the related test instructions is to be found in the abovementioned Announcement.
