Dynamics NAV is a legacy Microsoft ERP platform, but many organizations still operate NAV environments. This updated FAQ explains the questions NAV users should ask when evaluating Business Central modernization in 2026.
What Is Dynamics NAV?
Dynamics NAV was Microsoft’s ERP solution for small and midsize organizations. It supported finance, sales, purchasing, inventory, manufacturing and other business operations and later evolved into Dynamics 365 Business Central.
Is Dynamics NAV Still Supported?
Support depends on the exact NAV version and Microsoft’s lifecycle policies. Organizations should verify the version-specific lifecycle status rather than assuming that all NAV releases have the same support position.
Is Business Central the Replacement for NAV?
Yes. Business Central is the modern successor to the Dynamics NAV product line, but moving from NAV to Business Central requires a version-specific assessment.
Can NAV Be Upgraded Directly to Business Central 2026?
Not for every version. Microsoft’s current supported path to Business Central version 28 requires intermediate versions for older NAV releases. NAV 2015–2018, for example, follows a route through Business Central version 14 and version 25 before version 28. citeturn0search6turn0search10
Can NAV Be Migrated to Business Central Online?
Yes, but older NAV versions may need to be upgraded through supported Business Central on-premises versions before moving to Business Central Online. Microsoft publishes separate migration routes by source version. citeturn0search7
What Happens to NAV Customizations?
Customizations must be assessed individually. Older C/AL modifications may need to be converted to AL extensions, redesigned, replaced with standard functionality or retired.
Can NAV Data Be Migrated?
Data migration is possible, but the exact approach depends on the source version, data structure, customizations and target deployment. Data quality should be assessed before the migration begins.
What Are the Benefits of Business Central?
- Modern cloud option
- Regular Microsoft updates
- Microsoft 365 and Power Platform integration
- Modern analytics
- Extension-based customization
- Growing Copilot and agent capabilities
Microsoft’s 2026 Business Central release wave includes continued investment in finance, supply chain, manufacturing, reporting, integrations and AI-assisted processes. citeturn0search1
Should We Choose Business Central Online or On-Premises?
Online can reduce infrastructure responsibility and provide Microsoft’s SaaS update model. On-premises may still fit organizations with specific infrastructure, compliance, integration or operational requirements.
What Should Be Checked Before an Upgrade?
- Exact NAV version
- Custom code and modified objects
- Third-party extensions
- Integrations
- Data quality
- Reports and workflows
- Security and permissions
- Target deployment
- Supported Microsoft upgrade path
- Testing and cutover requirements
Final Takeaway
NAV users should approach modernization as a business and technology project. Confirm the current version, assess customizations and data, select the right Business Central target and follow Microsoft’s current supported migration path.
