One-stop-shop for IBM i/AS400 Services

IBMi/AS400 Services is a broad spectrum of support encompassing hardware and software aid, vigilant system surveillance, efficient troubleshooting, regular maintenance, strategic upgrades, and stringent security measures. Offerings within this service include adept AS400 administrative support and management, comprehensive disaster recovery solutions, and replication management for ensuring high availability, alongside detailed performance analysis, all aimed at optimizing system reliability and performance.

Based on over 15+ years of AS400 services delivery, most organizations are not in a single state. Some systems require stable, day-to-day support, while others are preparing for modernization. Many environments operate in both modes at the same time, depending on business priorities and risk tolerance.

A maintain-first approach is appropriate when system stability and continuity are the top priorities. This typically applies when the AS400 platform supports core business operations that cannot tolerate disruption.

Maintenance-focused environments usually require:

• Skilled RPG, CL, and DB2 support
• Well-defined support processes and quality metrics
• Knowledge transfer and system documentation
• Continuous optimization to control operating costs

Modernization becomes relevant when the business needs greater flexibility, improved user experience, or better integration with newer systems, without replacing the core platform outright.

Modernization efforts often include:

• Controlled reengineering and refactoring
• UI transformation beyond 5250 screens
• Performance and scalability improvements
• Readiness for modern integrations and services

Modernization is handled in a controlled, phased manner. This may include refactoring code, reengineering workflows, modernizing interfaces, improving performance, and enabling integrations, while preserving existing business logic and minimizing risk.

Yes. In many AS400 environments, maintenance and modernization run in parallel. Critical systems remain stable and supported while selected components are modernized in a controlled, low-risk manner.

Nalashaa provides L2 and L3 AS400 support, including maintenance, bug fixes, enhancements, DB2 administration, tool support, proactive monitoring, upgrades, and user training. Support is delivered with defined processes, metrics, and escalation models.

Yes. We design and implement integrations between AS400 systems and external platforms such as ERP, CRM, ecommerce, and cloud applications. This includes API development, custom adapters, parsers, and integration testing.

Yes. Front-end modernization can be gradual. We often start with user-facing screens, transforming 5250 interfaces into web or mobile experiences while keeping the underlying RPG logic intact. This reduces risk and accelerates adoption.

Our technology choices include tools and frameworks for UI modernization, API enablement, database optimization, hybrid cloud integration, automation, and DevOps. The selection depends on the system architecture, business goals, and modernization scope.

Yes. AS400 workloads can be re-hosted to the cloud using a lift-and-shift model that preserves application logic, interfaces, and services. This approach reduces infrastructure dependency while maintaining system behavior.

We enable AS400 data offloading for analytics through batch and real-time pipelines. Data from DB2, logs, and reports can be ingested into cloud storage, processed through ETL pipelines, and made available for dashboards, BI tools, and advanced analytics.

Knowledge transition is structured and phased. It begins with system analysis and documentation, followed by guided support and gradual ownership transfer. This ensures continuity, reduces dependency on individuals, and creates a sustainable support model.

Yes. Nalashaa often works alongside internal teams, handling operational support and enhancements while in-house resources focus on strategic initiatives such as modernization or new business capabilities.
