Why migrate from AS/400 systems?

Maintaining a high-performance IT infrastructure is the foundation of competitiveness for any leader concerned with the long-term sustainability of their operations. Yet, many organisations still find themselves trapped by obsolete architectures, desperately seeking to reconcile technological legacy with modern agility, particularly during the transition to an Enterprise Resource Planning (ERP) system on AS/400 platforms. This digital transformation is not merely a simple server change; it represents a true strategic lever to optimise your business processes and secure your critical data flows against new market challenges.

Understanding the stakes of this migration is essential to anticipate the risks associated with software obsolescence and exponential maintenance costs. Through this analysis, we will explore the major issues related to using ERP on the AS/400 platform, from the increasing difficulty in finding qualified experts to the impact of the user interface on employee productivity. You will discover how adopting cloud solutions and integrated software packages can transform your technical constraints into genuine opportunities for growth and innovation for your business.

The AS/400 system is an IT framework that is increasingly reaching its limits. As a result, very few companies continue to rely on this IBM solution. There are several reasons behind the progressive abandonment of this operating system. Here, we explore some of the key reasons why you should transition away from your AS/400 system.

AS/400 maintenance is costly and restrictive

What is AS/400 software? ? That may be what you are wondering. Regarding this point, it is important to note that AS/400 is an architecture composed of both hardware (the AS400) and software (the OS/400) components. It includes a database as well as numerous functions.

Over time, organizations using AS/400 have developed numerous system integrations. These integrations complicate maintenance and require highly skilled personnel to manage them. Retaining such expertise comes with a cost that can appear quite high for companies.

However, other solutions exist to significantly reduce both the expenses and the time required for operating system maintenance. SaaS ERP is one of them.

Regarding SaaS ERP, IT management is outsourced directly to a service provider. Update fees are included in the subscription cost, unlike the AS/400, where licensing fees are very high.

The obsolete state of the AS/400 is putting employees at a disadvantage

The AS/400 interface has remained unchanged over the years, maintaining the same appearance for all user companies. Beyond being difficult to use, the interface is also cumbersome and lacks ergonomic design. In other words, the AS/400 no longer meets the expectations of employees in modern enterprises.

As technology advances, users are increasingly seeking more seamless experiences. This is why more and more companies are opting for ERP systems. These enterprise management technologies are more intuitive, engaging, and user-friendly.

AS/400 is causing a skilled labor shortage within the company

As the AS/400 ages, specialists in its solutions are also becoming increasingly scarce. It is a technology that is difficult to upgrade. Consequently, very few people are currently qualified to program this system, as the number of AS/400 newcomers is extremely low.

Indeed, recent graduates are increasingly drawn to subtle and modern solutions. Therefore, to keep your current system up to date, your company stands to benefit significantly from transitioning to a new operating system.

By choosing an ERP SaaS, for example, your company eliminates the need for in-house IT management while benefiting from regular updates. This ERP software is cloud-based and available via a monthly subscription per user.

Your company’s growth is being hindered by AS/400 incompatibility

SaaS, DMS solutions, the Internet of Things, and AI offer significant real-world value to companies. They provide immense flexibility by adapting to specific projects, ultimately driving increased effectiveness and efficiency within the organization.

Migrating from AS/400 to a modern ERP or OGI offers numerous advantages. For instance, it enables better control over company processes and activities, allows for precise workflow organization, and integrates all areas of your business into a single system. By reducing administrative overhead, an ERP (Enterprise Resource Planning) system drives productivity and innovation.

Summary of the challenges involved in migrating your AS/400 system

Moving away from an AS/400 system represents a major strategic turning point for the long-term viability of your infrastructure. Between exorbitant maintenance costs, obsolete interfaces, and the increasing difficulty of recruiting experts, transitioning to a SaaS-based ERP is becoming an operational necessity. By replacing this AS/400 software with a modern cloud solution, you free your company from technical constraints to focus on innovation. This transition towards a more agile ERP model allows you to unify your processes while ensuring the flexibility indispensable to meeting today’s market evolutions.

Today’s technological evolution requires decision-makers to engage in deep reflection regarding the long-term viability of their IT infrastructure. Maintaining an AS/400 system represents a major strategic challenge, characterised by rising maintenance costs, an obsolete user interface, and an increasing difficulty in recruiting experts capable of mastering such specific AS/400 software. Beyond the purely technical issue, the real stakes lie in your organisation’s ability to adapt to new industry standards. By remaining anchored to a rigid architecture, your company risks losing its competitive edge, due to an inability to integrate major innovations such as artificial intelligence or real-time data flows, which are nonetheless essential to modern growth.

Opting for a transition towards a SaaS-based Enterprise Resource Planning (ERP) system constitutes a powerful lever for transformation, streamlining your processes and unlocking your employees’ potential. By migrating to cloud solutions, you are not merely replacing an outdated system with software more efficient than the AS/400; you are adopting an agility strategy that reduces administrative burdens and fosters continuous innovation. Modernising your digital ecosystem is an investment in the future, ensuring better control over your workflows and increased accessibility for your teams. To anticipate shifts within your sector and secure your growth trajectory, it is now essential to precisely analyse your current IT estate to identify the most cost-effective migration opportunities for your organisation.
