AX4 & Legacy ERP Systems – Why Upgrading to a Modern System Is Inevitable

Companies still working with Microsoft Dynamics AX4 or comparable legacy ERP systems are increasingly facing a key challenge: how long can these platforms continue to meet the growing demands of the digital economy?


Below, we examine the reasons, risks and opportunities associated with upgrading – and why now is the right time to do so.  

The reality of AX4 and legacy ERP systems

Dynamics AX4 was released in 2006. Since then, the business world has changed radically. Topics such as cloud computing, automation, artificial intelligence and real-time analytics now dominate the ERP market.

  • Nevertheless, many companies still rely on AX4 or similar solutions – often because:

  • the systems have been customised over many years,

  • a change seemed too expensive or too complex,

  • ‘it has worked so far’.

However, these arguments are becoming increasingly less relevant.

 

Risks of remaining on legacy systems

Sticking with AX4 or similar ERP versions has significant disadvantages:

  • End of support: Microsoft no longer offers active support or security updates. Companies are left to their own devices in the event of malfunctions.

  • Cybersecurity risks: Outdated systems are vulnerable to attacks and often no longer meet current compliance requirements (e.g. GDPR).

  • High operating costs: Maintenance, infrastructure and workarounds cause hidden costs.

  • Lack of innovation: Modern features such as AI-powered forecasting, automation and cloud integration are completely absent.

  • Difficult integration: Legacy systems are difficult to link to modern tools such as Power BI, Microsoft Teams or CRM systems.

In short, those who remain on AX4 run the risk of falling behind the competition.

 

Why Dynamics 365 is the logical next step

Microsoft Dynamics 365 is much more than an update – it is a future-proof platform that combines cloud, AI and flexibility. The most important advantages at a glance:

  • Cloud-first approach: Location-independent access, high availability, automatic updates.

  • Scalability: Systems grow with business requirements.

  • Seamless integration: Office 365, Teams, Power Platform, BI and CRM are deeply integrated.

  • Modularity: Companies can modernise step by step – finance, supply chain, HR and more.

  • Intelligence through AI: Automated workflows, real-time analytics, machine learning for better decisions.

  • Regular updates: Security and feature updates run continuously in the background.

 

The path from AX4 to Dynamics 365

An upgrade is not a simple ‘technology change’, but a digital transformation. Successful projects usually follow these steps:

  1. Analysis phase – Taking stock of current processes and systems.

  2. Strategic planning – Defining goals, priorities and roadmap.

  3. Data migration – Ensuring that master data, histories and interfaces are transferred correctly.

  4. Process optimisation – Taking advantage of the opportunity to redesign inefficient processes.

  5. Training & change management – Empowering employees to use the new functions efficiently.

  6. Go-live & support – Gradual introduction with close support from experts.


Conclusion: Not if, but when

The transition from AX4 or a legacy ERP system to a modern solution such as Dynamics 365 is not an option, but a necessity. The risks of outdated systems are constantly increasing, while the opportunities offered by modern platforms are enormous.


Companies that act now secure:

  • Future viability

  • Agility in dynamic markets

  • and a clear competitive advantage.
