Eliminating License Risk with Open Source: Migrating 400+ …

Back to all talks

A Tier-1 bank was running more than 80 applications on a document-oriented database estate spanning 400+ instances and 35TB of data. Changes in licensing terms introduced cost pressure and long-term architectural constraints. This session details the technical and governance approach taken to migrate those workloads without application rewrites. We will cover estate discovery, compatibility validation, migration sequencing, backup redesign with point-in-time recovery, and monitoring consolidation across hundreds of nodes. We will share practical lessons for tech teams managing large-scale database platforms in financial services.
