AS400 modernization refers to the process of updating or upgrading systems, applications, and infrastructure built on the IBM AS/400 platform, now known as IBM i. The AS/400, introduced in the late 1980s, was renowned for its stability and reliability, but many organizations still rely on legacy applications running on this platform. Modernization of AS/400 systems typically involves several steps: Migration to New Hardware: Upgrading the hardware infrastructure to more modern IBM i servers or migrating to cloud-based solutions like IBM Cloud for IBM i. Application Modernization: This involves updating or replacing legacy applications running on the AS/400 platform. It may include rewriting applications using modern programming languages such as Java or .NET, refactoring existing code, or rearchitecting applications to be more modular and scalable. User Interface Modernization: Many AS/400 applications have outdated user interfaces. Modernization efforts often focus on improving the user experience by redesigning user interfaces to be more intuitive and user-friendly, often using web-based or mobile interfaces. Integration with Modern Systems: Integrating AS/400 systems with other modern systems and technologies, such as cloud services, APIs, and IoT devices, to enhance functionality, scalability, and interoperability. Data Modernization: Updating data storage and management practices to align with modern standards and technologies, such as migrating from legacy databases to relational databases like IBM Db2 or adopting NoSQL databases where appropriate. Security Enhancements: Strengthening security measures to protect against modern threats, including implementing multi-factor authentication, encryption, and regularly updating security patches. Training and Skill Development: Providing training and skill development opportunities for IT staff to ensure they have the necessary expertise to maintain and support modernized AS/400 systems. Modernizing AS/400 systems offers several benefits, including improved performance, scalability, security, and agility, as well as reduced maintenance costs and increased competitiveness in the digital age. However, it also requires careful planning, investment, and collaboration between IT teams, business stakeholders, and external partners to ensure successful execution. Read more: AS400 Modernization
