AS400 Cloud MigrationOptimize Legacy Infrastructure for Modern Enterprise Demands
Enterprises with aging AS400 systems face mounting costs and shrinking support as fewer experts understand these legacy platforms. These systems can’t scale quickly when business demands change, forcing a difficult trade-off between innovation and stability. This is one of the reasons why many enterprise-level organizations using AS400 (Application System/400) are actively considering iSeries migration services to overcome the challenges associated with legacy IBM iSeries Servers. With migration of AS400 to Azure, AWS, or Google Cloud, businesses reduce capital expenditure, improve agility, and eliminate legacy usability constraints. They also strengthen data security, enable cloud readiness, and prepare themselves for large-scale transformation.
Damco evaluates your AS400 environment to build a clear, risk-assessed migration roadmap. Our approach covers application migration, database conversion, batch job transition, and infrastructure setup, including hardware, software, licensing, and peripheral upgrades. We manage the full transition to ensure data integrity, operational continuity, and minimal business disruption. For organizations wanting ongoing management, we also offer managed services with post-migration support and optimization.

Frequently Asked Questions
AS400 and IBM i are essentially the same platform with different names. AS400 was the original name introduced in 1988. IBM rebranded it as iSeries in 2000, then System i in 2006, and finally IBM i in 2008. IBM i represents the modern, evolved version with enhanced capabilities while maintaining complete backward compatibility with original AS400 applications.
Approaches for migrating AS400 systems to the cloud typically fall into five categories, including lift-and-shift, replatforming, refactoring, replacing, and hybrid deployment. Organizations may also pursue phased migrations, containerization using technologies like Docker, or managed IBM i cloud services, depending on complexity and objectives.
The AS400 platform, now IBM i, is far from outdated. It's evolved into a modern system supporting cloud deployment, containerization, contemporary programming languages, and advanced security features. Thousands of organizations trust IBM i for mission-critical applications due to its exceptional uptime, scalability, and integration capabilities.
AS400 is used by many enterprise-level organizations for powering mission-critical workloads and applications. Since it comes with firewall capabilities and a web-enabled server, it is ideal for running eCommerce businesses. Besides this, AS400 is used across industries that demand reliability, such as manufacturing and production.
Depending on complexity, data volume, and system dependencies, the duration of migration can be anywhere from a few weeks to a couple of months. Small applications with minimal customization may take 3-6 months, while large enterprise systems might require 18-24 months. Our teams follow an agile approach to migrate AS400 to Azure, AWS, or Google Cloud from on premises with the highest quality standards.
