Orchestrate your Digital Ecosystem with our IBM iSeries AS400 Modernization Services

A modernization partner can assess the existing applications, business logic, integrations, and user requirements to identify which components can be improved incrementally. Potential initiatives include RPG refactoring, application re-engineering, UI/UX improvements, API enablement, and database modernization. United Techno provides AS400 modernization services focused on transforming legacy IBM i environments while preserving the value of existing applications where appropriate. The modernization strategy should be tailored to the current architecture and business priorities.

AS400 migration primarily focuses on moving data, applications, workloads, or infrastructure to a different environment. AS400 modernization focuses on improving the capabilities, maintainability, interfaces, architecture, or functionality of existing systems. The two can be performed together, but they are not identical. If your main objective is to relocate a workload, migration planning may be the priority. If your objective is to improve application usability, maintainability, or integration, modernization may be more appropriate. A technical assessment can help determine the right combination.

United Techno’s AS400 modernization service page identifies UI/UX modernization and extending AS400 systems across web and mobile channels as part of its service offering. The feasibility of a particular interface modernization project depends on the existing application architecture, business logic, integration options, security requirements, and desired user experience. A technical assessment should establish which functionality can be exposed or redesigned and how the new interface will interact with the underlying IBM i applications.

RPG modernization can be considered when application code is difficult to understand, maintain, or enhance. Depending on the application, improvements may include refactoring, modularization, changes to coding practices, and documentation of business logic. The appropriate approach should preserve required functionality and account for dependencies across applications and databases. United Techno offers RPG-related modernization capabilities within its AS400 services. The scope should be defined through an assessment of your codebase, business processes, and technical objectives.

Yes, API enablement and system integration can be part of an IBM i modernization strategy. The project should first identify the business capabilities that need to be exposed, the underlying application logic, security requirements, data structures, and target systems. United Techno’s modernization offering includes system integration and API-related capabilities. The final architecture should be based on the requirements of your existing applications and the modern systems they need to communicate with.

Start with application discovery and documentation of business processes, dependencies, interfaces, and data requirements. Modernization can then be planned in stages, prioritizing components based on business value, technical risk, and implementation feasibility. Testing should confirm that essential business behavior is preserved after each change. United Techno can assess your IBM i modernization requirements and help define a roadmap that considers existing application investments alongside desired improvements.

Assess the provider’s experience with IBM i applications, RPG technologies, databases, integration architecture, modernization planning, testing, and documentation. Ask how it approaches legacy application discovery, dependency analysis, incremental delivery, and change management. Also evaluate whether the proposed approach fits your business processes and operational constraints. United Techno’s AS400 modernization offering covers areas such as application re-engineering, RPG modernization, UI/UX modernization, system integration, and cloud migration. The specific experience and delivery scope should be verified for your project.

A modernization roadmap should begin with an assessment of the current applications, business dependencies, technical limitations, and desired business outcomes. Prioritize initiatives based on factors such as business impact, maintainability, user experience, integration needs, security requirements, and implementation complexity. Define measurable outcomes for each phase, such as completed application improvements, validated integrations, or improved operational processes. United Techno can discuss your modernization objectives and help establish an appropriate assessment and implementation approach. Specific outcomes should be agreed upon based on the project scope and baseline measurements.
