For decades, the AS400 has been a dependable presence in the realm of business computing. However, as the digital landscape advances, cloud computing has emerged as the new standard, offering scalability, flexibility, and cost-efficiency.

AS400 cloud migration is the gateway to accessing these advantages while preserving your invaluable legacy data and applications. In this blog post, we will delve into the essentials of AS400 cloud migration, offering insights, best practices, and a roadmap to ensure a seamless transition.

AS400 Cloud Migration

Before we delve into the migration process, let’s take a moment to comprehend AS400 (IBM iSeries) and why migrating it to the cloud is such a compelling proposition:

1. Legacy System: The AS400 platform, also known as IBM iSeries, has been a reliable workhorse for businesses over the years, offering unwavering performance and dependability. Nevertheless, its aging hardware presents mounting challenges and costs for maintenance.
2. Scalability and Flexibility: Cloud platforms like AWS, Azure, and Google Cloud provide the scalability and flexibility needed to adapt to evolving business requirements. This enables effortless resource scaling, resulting in cost savings during periods of lower demand.
3. Cost-Efficiency: Cloud migration often translates into cost savings by eliminating the necessity for on-premises hardware maintenance and trimming operational expenditures.
4. Security and Compliance: Cloud service providers offer robust security measures and compliance certifications, simplifying adherence to regulatory standards and safeguarding sensitive data.
5. Business Continuity: Cloud-based AS400 instances come equipped with built-in disaster recovery and high availability solutions, ensuring uninterrupted access to vital business applications even in the face of unforeseen disruptions.

Having highlighted the benefits, let’s now explore the steps involved in AS400 cloud migration.
