【AI & Modernization】Boomi, OpenLegacy, and Power Solutions to Host Webinar: 'AS/400 and Mainframes Can Become Connected Assets Without Modernization'

Boomi K.K. (Shibuya-ku, Tokyo; CEO: Eitaro Kono, hereinafter 'Boomi'), provider of the 'Boomi Enterprise Platform'—a foundation for transforming data into value for AI—will co-host a webinar on Thursday, July 23, 2026, from 11:00 to 12:00, titled 'AS/400 / Mainframes Can Become “Externally Connected Assets” Without Modernization—The Practical Path to DX: Keep Core Systems Running, Start by Connecting.' The event is free and requires prior registration.

This webinar will present a comprehensive flow for leveraging AS/400 and IBM mainframes in their current state—without modernization—to connect with external systems, and further, to utilize the business data residing within core systems for AI applications.

◼️ Background

As demand grows for integration with EDI, SaaS, and AI systems, AS/400 and IBM mainframes remain at the heart of enterprise operations as 'untouchable, never-to-be-stopped' core systems. Each new integration often requires custom development, leading to accumulating costs and time. Eventually, organizations circle back to the debate: 'Should we just modernize everything?' Many organizations are trapped in this cycle.

Responding to concerns such as 'We can’t stop the core system, but we need external connectivity,' 'The cost and time for each integration are unsustainable,' and 'Who will manage and govern the growing number of integration mechanisms?'—this webinar brings together three experts: OpenLegacy, specialists in legacy system API modernization; Boomi, a global iPaaS provider; and Power Solutions, which bridges the two and supports implementation. Together, they will present a three-part roadmap for connecting AS/400 and IBM mainframes to external systems without modernization, transforming them into assets usable for business and AI.

Furthermore, this webinar goes beyond simple external connectivity. It will demonstrate how to extract long-stored business data from AS/400 and IBM mainframes into formats usable by AI. The session will show how to transform dormant data into structured data assets that generative AI and AI agents can leverage for customer service, business decision-making, and analytics—offering a practical approach to 'legacy data AI utilization' without waiting for full system modernization.

Attendees will gain actionable insights to transform their 'unstoppable core systems' from bottlenecks into 'connected, AI-activated assets.'

◼️ Session Highlights

- A practical, co-hosted solution for connecting AS/400 and IBM mainframes externally—without modernization or downtime
