Your LegacySystems,AI-PoWered.
We don't rip and replace. We wrap, bridge, and augment injecting AI agents, NLP overlays, and intelligent middleware directly into your AS/400s, ERPs, and monolithic codebases.
Technical Debt vs.
AI-First Architecture
Your enterprise is paralyzed. AS/400 mainframes, decades-old ERPs, and monolithic Java apps hold your most valuable data but are completely disconnected from the AI revolution.
Traditional migration projects run for years, cost millions, and fail at alarming rates. There is a better approach: augment rather than replace.
Four Modernization
Pathways
Integrating LLMs with systems built in the 1990s requires a specific engineering discipline. We've built it battle-tested on real enterprises.
Intelligent API Wrappers
Expose legacy databases through secure, AI-native REST layers
Your AS/400 has no API. We build one a smart middleware layer that translates modern requests into legacy queries, cached, secured, and fully observable.
AI Code Refactoring
Translate COBOL, Fortran & legacy Java into modern microservices
Fine-tuned models map your business logic, restructure variable trees, and generate Python/Go equivalents verified by automated parallel testing suites.
NLP Overlays
Replace green-screen terminals with natural language interfaces
Employees type plain English. The AI translates into exact legacy queries behind the scenes no retraining, no disruption, instant productivity gains.
Unstructured Data Mining
Clean, structure and migrate decades of trapped legacy data
Vision AI and LLM parsers process raw mainframe logs, legacy PDFs, and unformatted print sheets into searchable vector databases within days.

In Action
Transforming Legacy
Industries
Vistaran helps compliance-driven industries modernize without risking operational continuity.
Loan officers manually key data between modern CRM tools and 30-year-old core-banking mainframes taking days per application.
Vistaran bridges Fiserv/Jack Henry databases with AI credit-assessment agents. Automated reads/writes eliminate all manual transfer.
Safe. Phased.
Fully Tested.
When dealing with the backbone of your enterprise, “move fast and break things” is never an option.
Strangler Fig Pattern
We never migrate everything at once. Legacy modules are wrapped or replaced one service at a time ensuring absolute operational continuity and zero downtime windows.
Parallel Test Suites
Every AI-translated codebase runs against the original simultaneously. We verify 100% of inputs produce identical outputs before any legacy module is decommissioned.
Security Guardrails
Legacy systems are inherently vulnerable. We layer OAuth, SSO, rate limiting, and audit logging on every integration insulating your mainframes from modern threats.
