Modernizing UK bank’s legacy systems from IBM COBOL to Microfocus COBOL
Overview.
A prominent UK bank, known for its diverse offerings and commitment to innovation, sought to modernize its core banking platform. To meet the demands of a rapidly changing financial landscape, the bank decided to migrate from a traditional mainframe setup to the cloud. Coforge was brought in to facilitate this complex transition. While the move promised scalability, agility, and cost savings, it also presented substantial challenges.
Link-edit failures: Challenges in combining object modules.
Unresolved external references: Addressing references to external functions or data.
Run-time issues: Unexpected behavior during program execution.
Manual code conversion: Handling differences between COBOL versions.
Solution.
Coforge stepped in with a comprehensive approach and enabled hassle-free migration of the COBOL versions along with some extraordinary features in the solution.
Key highlights of the solution:
Technology migration: Smooth transition from IBM Mainframe COBOL to Microfocus COBOL and migration from DB2 to Oracle on a UNIX platform.
Module and API updates: All modules and APIs underwent a revamp, pointing to new endpoints that referred to the Oracle DB instead of DB2.
Cloud hosting: The new environment now thrives on a UNIX platform, ready for cloud hosting.
Ongoing support: Our development, testing, and production teams ensured a successful migration and continue to support the new environment.
Dependency analysis and testing: Rigorous analysis and thorough testing to uncover code dependencies, enhance reliability and stability of the software.
Runtime testing and monitoring: Early detection and mitigation of run-time issues via boundary and stress testing.
Automated code conversion: Leverage automated tools for code conversion, efficient transformation and reduced manual effort.
