XLF•Mainframe modernization seen as a strategic priority
- Indra’s Minsait flagged core banking mainframe modernisation as a strategic priority as regulation, AI adoption, and faster product cycles intensify.
- The report estimates about 80% of enterprise data resides or originates on mainframes, processing roughly 30 million transactions daily.
- The study says 92% of the world’s top banks still use mainframes, and 90% of CIOs see new digital apps remaining dependent.
- Agentic AI is cited as a risk-reduction tool to analyse legacy code, recover undocumented business rules, generate documentation, and speed conversion.
- Gradual migration is highlighted as critical, with parallel operation of legacy and modern platforms to protect continuity during large-scale transitions.
