DekaBank replatforms with GFT

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

• Modernise 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 at 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

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

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

• Definition of a modern, container-based target architecture and support client during deployment
• Migration of the selected application modules and transfer of host-specific elements, such as sequential files, into platform-compatible solutions. Part of the migration were 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

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
