5 Common AS400 Challenges and How Consulting Services Help Solve Them

 Introduction

The IBM iSeries AS400 platform has long been recognized for its stability, security, and performance. Many organizations still rely on it for mission-critical operations. However, with evolving technology and business demands, companies often face several challenges in managing and modernizing their AS400 systems.

Rather than retiring a proven system, businesses are choosing to optimize it — and that’s where expert IBM iSeries AS400 Consulting Services & Implementation comes in. This article outlines five common AS400 challenges and how professional consulting can help businesses overcome them efficiently.

1. Outdated Interfaces and User Experience

The Challenge:
Many AS400 systems still rely on green-screen interfaces, which are difficult for modern users to navigate.

The Solution:
Consulting services can modernize user interfaces without disrupting the core system. By leveraging web and mobile-friendly layers over existing infrastructure, businesses can improve user adoption and streamline workflows — all while preserving backend stability.

2. Lack of Skilled Resources

The Challenge:
As experienced AS400 developers retire, finding in-house talent to support and enhance the system becomes increasingly difficult.

The Solution:
AS400 consulting firms provide access to skilled professionals with deep knowledge of RPG, CL, and DB2. United Techno’s consultants, for example, fill in these gaps and ensure continuous system performance, troubleshooting, and modernization planning.

3. Integration with Modern Applications

The Challenge:
AS400 systems often operate in isolation, creating data silos and hindering integration with newer enterprise tools like CRMs, ERPs, and cloud platforms.

The Solution:
Consultants help bridge this gap by developing robust integration solutions using APIs, middleware, and ETL tools. This enables real-time data sharing across systems and ensures that AS400 becomes a connected part of your IT ecosystem.

4. Scalability and Performance Issues

The Challenge:
Legacy configurations may not scale well as business grows, leading to system slowdowns or limitations.

The Solution:
Through performance assessments, capacity planning, and strategic upgrades, consulting experts help businesses optimize their AS400 environments to support growth without costly overhauls.

5. Security and Compliance Risks

The Challenge:
With increasing cybersecurity threats and regulatory requirements, older AS400 setups may not meet today’s standards.

The Solution:
AS400 consultants conduct security audits, implement role-based access controls, enable encryption, and align your systems with compliance standards. This ensures your data stays protected and your business remains audit-ready.
