Microsoft Dynamics NAV Support, Upgrades & Migration
End-to-End ERP Expertise for Modern, Regulated Businesses
As organizations evolve, legacy Microsoft Dynamics NAV environments often struggle to keep pace. Outdated versions limit integration, slow down reporting, and introduce compliance and security risks. Customizations can block upgrades. Infrastructure becomes costly. Users lose confidence.
L&L Consulting delivers structured NAV modernization, whether you need expert support, a technical upgrade, a complete reimplementation or a full migration to Microsoft Dynamics 365 Business Central.
Our team of accountants, architects, certified trainers, Microsoft-certified experts, and MVPs brings decades of experience across Navision 1.0 → NAV 2018 to ensure your system is stable, compliant, and ready for the future.
Why Organizations Modernize NAV
- Legacy versions are slow, siloed, and costly to maintain
- Customizations block upgrades and create technical debt
- Increasing difficulty integrating with Microsoft 365, Power BI, and 3rd-party apps
- Security vulnerabilities due to lack of Microsoft patches
- Compliance exposure across SOX, HIPAA, FDA, ISO, CMMC
- Reporting limitations and manual workarounds
- Growing performance and infrastructure risks
