AS400 Cloud MigrationReimagine Legacy Systems for Modern Business 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, leaving companies in a fix to choose 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 AS400 cloud migration, businesses can mitigate potential data and security risks, poor usability and manageability, and lack of readiness for the cloud while reducing high capital expenditures (CapEx), improving agility & scalability, and driving digital transformation.
As a leading AS400 migration company, Damco evaluates the existing health status of AS400 Systems to devise a roadmap for hassle-free cloud migration. Under AS400 cloud migration, we follow the latest engineering approach to make the aging IBM System i competitive and future-ready.

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.
AS400 cloud migration approaches typically fall into five categories, including lift-and-shift, replat forming , 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The AS400 platform, now IBM i, is far from outdated.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 exceptional uptime, scalability, and integration capabilities.
AS400 is used by many enterprises 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 project duration 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. We follow an agile approach to migrate AS400 to Azure, AWS, or Google Cloud from on-premises with the highest quality standards.
