AI-Driven, Cloud-Ready Transformation for Legacy Systems

Talk to us
Apexon’s AI-driven modernization framework help businesses enhance legacy mainframe workloads with cloud-native agility, scalability, and automation. This approach reduces costs while accelerating digital transformation—ensuring business continuity without disruption.

The Challenge

Breaking Free from Mainframe Constraints

Legacy mainframes remain integral to business operations but are challenged by high costs, limited scalability, and slow adaptability. The lack of modern integration capabilities, real-time data access, and agility restricts digital transformation.

BFSI and other industries struggle with poor documentation, monolithic architectures, and rising maintenance overheads—all of which limit innovation. Apexon enables seamless modernization, blending cloud-native technologies, API-first approaches, and AI automation to create scalable, cost-effective solutions while maintaining business continuity.

What we do

Tailored Modernization for Maximum Impact

Apexon’s Mainframe Modernization Services transform legacy environments into scalable, future-ready architectures, ensuring cost efficiency, agility, and seamless integration with cloud-native ecosystems. Unlike conventional lift-and-shift approaches, our methodology decomposes monolithic applications, extracts critical business logic, and enables phased modernization—preserving business continuity while accelerating innovation.

  • Rehosting & Reengineering – Optimize workloads by rehosting or reengineering legacy applications, leveraging AI-driven automation to accelerate mainframe-to-cloud transitions.
  • Native Migration & Code Modernization – Enable language transformation (COBOL, PL/I to Java, Python) while introducing API-first, microservices-based architectures for interoperability.
  • Data & Database Modernization – Migrate IMS DB, DB2, VSAM datasets to modern platforms while enhancing analytics, reducing storage costs, and ensuring high availability.
  • Functional & UI Modernization – Upgrade user interfaces and workflow automation while preserving core business functions, reducing complexity, and improving user experience.
  • Extracting Business Rules & Knowledge Mining – Use GenAI-powered reverse engineering to extract hidden business logic, enabling modularization and process automation.
  • Strategic Risk-Free Decommissioning – Identify and retire non-essential applications, ensuring compliance while optimizing operational costs.
