Successful modernization does not require a risky big-bang migration. T-Systems helps financial institutions renew core platforms step by step, from mainframe modernization and SAP S/4HANA transformation to ServiceNow-based workflows. A clean-core approach, rigorous testing and planned cut-overs reduce risk while maintaining business continuity and enabling innovation.
Both can be the right choice. Many core banking and insurance systems still run reliably on the mainframe and can be more cost-effective to optimize than replace. T-Systems assesses your application portfolio and identifies three paths: modernize in place with newer hardware, automation and DevOps; move selected workloads to the cloud while keeping the mainframe as system of record; or migrate fully. The decision depends on risk, cost and available skills.
RISE with SAP bundles S/4HANA Cloud ERP, infrastructure, software licences and services under a single contract. A clean-core approach keeps ERP processes close to the SAP standard while moving custom functionality to extensions, reducing complexity and simplifying upgrades. T-Systems delivers RISE with SAP on private cloud infrastructure in German data centers and applies the same clean-core principles used in the transformation of Deutsche Telekom's ERP landscape.
Yes. Banks and insurers can run RISE with SAP on T-Systems private cloud infrastructure in Germany. The platform is designed to support regulatory, security and compliance requirements, including GDPR, ISO, SOC and BaFin outsourcing expectations. Finance, controlling, treasury and insurance-specific SAP workloads can be migrated with audit trails and access controls.
ServiceNow connects people, processes and systems on a single workflow platform. Banks and insurers use it for IT service management, operations, risk and compliance workflows, customer and claims services, and HR processes. T-Systems provides consulting, implementation, integration and managed services. For organizations with data sovereignty requirements, ServiceNow can also be deployed on the sovereign T Cloud, supporting greater control over data location and access.
Through staged cutovers, parallel runs and extensive testing. In a major modernization project, Union Investment migrated its DB2 database from IBM z14 to z16 and relocated its platform from Munich to Frankfurt, transferring around 80 terabytes of data while maintaining business continuity. For SAP, T-Systems uses proven migration factories and automated testing. For ServiceNow, we apply phased rollouts by process area to reduce risk and disruption.
Yes. Policy administration and claims systems are often business-critical and highly customized. T-Systems helps insurers modernize these environments by assessing the application landscape, stabilizing core systems, moving suitable workloads to the cloud, and building modern digital services around them. For example, Barmenia worked with T-Systems to introduce digital services, including an invoice payment app and a medical consultation app.
