Case Study: BGL BNP Paribas achieves 80–90% mainframe cost savings and 20% faster online performance with OpenText

Effective partnership delivers enhanced flexibility and substantial cost savings

BGL BNP Paribas (BGL BNPP), a market-leading financial services firm in Luxembourg, faced a sprawling 40-year mainframe environment—15 million lines of code, 20,000 JCLs and thousands of databases—that made maintenance slow, costly and hard to integrate with new digital channels. With corporate cost-reduction mandates and a need to support Java-based mobile and web services, the bank needed greater agility without losing access to core business logic.

Working with HP Professional Services and Micro Focus, BGL BNPP used Enterprise Analyzer to understand legacy code and migrated applications to a Linux-based environment using Micro Focus Enterprise Developer and Enterprise Server over 18 months. The move delivered mainframe-grade stability, cut operating costs to an estimated 10–20% of prior levels (80–90% savings) with full ROI within two years, improved online performance by 20% and reduced batch jobs from hours to minutes, while strengthening developer–operations collaboration.
