If your organization is still running Microsoft Dynamics NAV, it may feel stable on the surface. Transactions process. Reports run. The system technically works.
But that does not mean it is safe, cost-effective, or sustainable.
For many organizations, the decision to update NAV keeps getting pushed back because of budget concerns, internal resource constraints, or fear of disruption. Ironically, those same concerns are often made worse by waiting.
Today, staying on NAV introduces growing security risk, higher long-term costs, and operational limitations that directly impact IT teams, finance leaders, and operations executives.
Check out this article: The Hidden ERP Risks That Will Cost You in 2026
Why Updating NAV Is No Longer Optional
Microsoft Dynamics NAV is no longer actively developed. Support windows continue to shrink, and each year makes it harder and more expensive to maintain.
Organizations that delay the decision to update NAV often face challenges such as:
- Increased exposure to cybersecurity threats
- Compliance gaps tied to outdated infrastructure
- Higher costs to maintain servers, patches, and customizations
- Fewer available NAV-skilled resources in the market
Mid-market companies are now a primary target for cyberattacks, largely because legacy, on-prem ERP systems are easier to exploit. Unsupported or lightly maintained systems increase the risk of downtime, audits, and data loss.
Updating NAV is no longer just a technical decision. It is a business risk decision.
The Cost Myth That Keeps NAV Customers Stuck
One of the primary reasons firms don't want to increase NAV is because it costs money.
It can appear that staying on NAV is cheaper because you've already paid for the system. In reality, the total cost keeps rising up in ways that aren't as clear.
Some of the NAV costs that aren't clear are:
- Updating servers and keeping infrastructure up to date on a regular basis
- Tools for backing up data, recovering from disasters, and keeping things safe
- Getting help in an emergency
- More expensive labor because there aren’t enough workers who know how to use NAV
- Lost productivity because to workarounds that require physical labor
These costs are easy to overlook because they don't usually show up in one location.
Companies sometimes change the subject quickly when they compare these prices to those of a modern cloud ERP like Business Central.
What It Means to Upgrade NAV Today
For most companies, updating NAV does not mean applying another on-prem upgrade.
The modern path forward is to upgrade NAV by migrating to Dynamics 365 Business Central.
Microsoft's Dynamics 365 Business Central is a cloud-based ERP for growing enterprises that want greater security, built-in compliance, and constant innovation without having to worry about infrastructure..
When you transfer NAV to Business Central, you gain the following benefits:
- Updates for security and compliance happen automatically
- Less reliance on internal IT resources
- Costs of licensing that are obvious to see coming and that go up
- Enhancements to features without large upgrade plans
- Microsoft products like Power BI and Microsoft 365 work together without any problems.
This change turns ERP from a system that needs to be updated into a platform that changes with the business.
Why Timing Matters More Than Ever
There are a number of things that make NAV consumers feel that they need to move quickly right now.
First, cyberattacks targeting mid-market companies continue to rise. Legacy ERP environments are among the most vulnerable entry points.
Second, NAV end-of-support realities mean fewer safety nets when something breaks. Fixes take longer. Downtime lasts longer. Risk increases.
Third, the availability of skilled NAV professionals continues to decline. When expertise is scarce, response times slow and costs increase.
Waiting does not reduce risk. It compounds it.
How to Move Forward Without Guesswork
The smartest organizations do not rush into an ERP decision blindly. They start with clarity.
Before you lock yourself into a migration or upgrade timeline, it helps to step back and get a clear picture of what’s really going on today:
- Where security or compliance gaps might already exist
- How much your day-to-day operations rely on NAV customizations
- What infrastructure and support costs are quietly adding up
- Where the biggest risks would show up if something went wrong
Having that clarity lets readers make thoughtful, proactive decisions instead of reacting when problems force the issue.

Final Thought for IT, Finance, and Operations Leaders
Updating NAV is no longer about staying current with software. It is about protecting the business.
Organizations that take a proactive approach gain control over timing, cost, and risk. Those that wait often end up forced into decisions under pressure.
If NAV is still running your business, now is the right time to understand what it is truly costing you and what your safest path forward looks like.
