Case Study: Major UK Financial Organisation achieves successful mainframe and middleware upgrades with Agenor Technology

Major UK Financial Organisation - Customer Case Study

Major UK Financial Organisation needed to upgrade critical mainframe and middleware software across its test and production environments without disrupting day-to-day business operations. The projects affected 40 applications, including 23 critical systems, plus 14 distributed systems and 3 test environments, creating significant risk to stability, resilience, and vendor support compliance. Agenor Technology provided testing services to support these high-risk upgrades.

Agenor Technology delivered comprehensive regression testing, scoping, managing, and executing tests across multiple projects and platforms, including CICS, DB2, and z/OS upgrades, and coordinated post-delivery business checkout. The engagement produced 7,500 regression tests across 40 applications and 13 projects, with testing artefacts meeting governance and compliance requirements and successful rollout across all environments.
