Challenge

Transformation of the host-based application landscape while reducing operating costs

Modernize a key part of the existing core banking application by connecting the sales partners to the depot system with only minimal code changes
Replatform as an initial step in the transformation of business-critical applications with continuous cooperation with all existing peripheral systems and databases
Reduction of running costs for infrastructure and software by reducing MIPS, especially for reporting date processing (month-end/year-end)

Additional requirements for the migrated application:

Operability without emulation in the target environment
Ongoing maintenance by existing developers

Engagement

Modernization of the Cobol-based host application by building a modern target environment, migrating and commissioning relevant software

Infographic illustrating the step-by-step replatforming process for DekaBank with GFT and Anubex, from pre-migration to go-live. — An infographic detailing the replatforming process for DekaBank, including pre-migration, transformation, testing, and go-live stages. This visual represents GFT and Anubex's collaborative approach to automated application modernisation, ensuring seamless migration and enhanced performance for financial institutions.

GFT managed the end-to-end migration, including:

Definition of a modern, container-based target architecture and support for client during deployment
Migration of the selected application modules and transfer of host-specific elements, such as sequential files, into platform-compatible solutions. The migration included the job nets of the migrated application itself, as well as their embedding into the existing job net for all further host applications.
Documentation at all levels – from conception to operating manual – and coaching of employees

Benefit

Increased performance, boosted efficiency and reduced costs

Despite the necessary additional data exchange between host and Unix system, up to 90 minutes faster processing of the processes
Reduction of previously occurring additional MIPS costs for key date processing at the end of the month and year

"GFT’s high level of technical expertise enabled us to migrate a critical component of a Cobol-based host application to a modern, cloud-enabled infrastructure. In addition, GFT ensured the transfer of know-how to the Deka team as well as the necessary performance optimizations in the job flow."
