For years, Microsoft Dynamics NAV has been the ERP system of choice for thousands of SMEs. Reliable, robust, and tailored to business needs, it has enabled many companies to structure their processes. But in 2025, the question is crucial: is NAV still viable?
The answer is simple: not really. Sticking with an outdated version not only hinders innovation, it also poses a major risk to your business. Why? Because Microsoft support has evolved, regulatory requirements have become stricter, and cybersecurity has become a vital issue.
End of Microsoft support: a risk for your NAV ERP system
Microsoft announced several years ago that it would gradually phase out support for its Dynamics NAV ERP system. In practical terms, this means:
No more major updates: your ERP system will no longer benefit from functional upgrades.
Limited security patches: every vulnerability becomes a potential gateway for cyberattacks.
No official support: in the event of a bug or incident, you are on your own... or dependent on a service provider who cannot guarantee compliance. In 2025, NAV will be officially considered obsolete.
Microsoft is focusing its efforts on Dynamics 365 Business Central, its latest-generation ERP, a scalable, secure cloud solution that is interconnected with the Microsoft ecosystem (Power BI, Copilot AI, Microsoft 365).
Security: a growing threat for SMEs
As we know, cyberattacks are skyrocketing. According to the latest studies, 80% of SMEs that fall victim to an attack use outdated systems. Hackers target known vulnerabilities in obsolete software. With an outdated management system, you are exposed to:
Unpatched vulnerabilities because the systems are no longer updated: without patches, every vulnerability remains active.
GDPR/Nlpd risks: a data attack can result in financial penalties but also damage your reputation.
Ransomware: older ERPs are prime targets for blocking your business.
In short: staying on NAV puts your data, your customers, and your business at risk.
Compatibility: a barrier to innovation and growth
The world is changing fast: e-commerce, automation, AI, interoperability, etc. Companies need to connect their ERP to modern tools (Shopify, logistics platforms, CRM, BI). Problem: NAV can no longer keep up.
Limited integrations: modern APIs are not compatible with older versions.
Blocked digital projects: impossible to automate your flows or leverage AI.
Loss of competitiveness: your competitors are moving forward, while you remain stuck.
With Business Central, you get a cloud-based, open ERP system that is interconnected with Microsoft 365, Power BI, Copilot AI, and can be integrated with your business tools.
Regulatory developments: a legal and financial risk
Legal requirements are changing rapidly: electronic invoicing, VAT, tax reporting, accounting standards. An outdated ERP system cannot keep up with these changes, and the consequences can be serious:
Non-compliance: risk of fines and penalties.
Hidden costs: you have to opt for specific development in order to remain compliant, which ultimately incurs more costs.
Increased complexity: each update is complicated.
Business Central, on the other hand, is updated several times a year and automatically incorporates regulatory changes, ensuring ongoing compliance.
Why migrate to Microsoft Dynamics 365 Business Central ERP?
Migrating isn't just about avoiding risks. Above all, it's about seizing a strategic opportunity. Key benefits:
Enhanced security: automatic updates, cloud protection.
Mobility and collaboration: access anywhere, integration with Teams and Microsoft 365.
