For many organisations, Microsoft Dynamics NAV (older versions) has been a trusted foundation for managing finance, business operations, and business processes. However, as technology evolves, many businesses and companies are finding that legacy software can quickly become a barrier to innovation, integration, and business growth.
Delaying an upgrade from NAV to Business Central could raise costs by 15%, as each yearly version release increases complexity and expense.
Migrating to Microsoft Dynamics 365 Business Central is more than an upgrade – it’s a strategic move towards modern ERP software designed for flexibility, efficiency, and scalability in the cloud.
At Zenzero, we help businesses transition seamlessly from NAV to Business Central with a structured, low-risk approach tailored to your organisation.
Why Upgrade from Dynamics NAV to Business Central?
Older NAV systems often limit your ability to adopt new technologies, automate processes, and integrate with modern tools. Business Central removes these limitations and empowers your business to boost efficiency through automation and modern technology, streamlining operations and improving overall performance. Carefully decide between available Microsoft ERP solutions to ensure you choose the best fit for your business needs.

Auditing your NAV system
Auditing your Microsoft Dynamics NAV system is a crucial first step in preparing for a successful upgrade to Dynamics 365 Business Central. This process ensures your business is fully aware of its current solution, identifies potential risks, and sets a clear path for the upgrade process.
A comprehensive audit evaluates your NAV system’s version, data structures, custom code, and integrations with other Microsoft products. By understanding the details of your current NAV system, you can make informed decisions about your business central upgrade – whether you choose to migrate, re-implement, or stay on premises.
Understanding the NAV to Business Central upgrade process
The upgrade process from Microsoft NAV to Dynamics Business Central can vary depending on your current NAV version, data structures, and business needs.
At a high level, the migration process includes:
- Assessment of your current solution:
Reviewing your NAV system, database, code, and customisations. - Planning the upgrade:
Deciding between a technical nav upgrade, a full re implementation, or a hybrid approach. - Data migration:
Moving critical data securely into the new system, ensuring integrity and accuracy. - Extension development:
Replacing legacy object designer customisations with modern extensions. - Testing and validation:
Ensuring all business processes function correctly in the new version. - Go-live and support:
Deploying your Business Central upgrade with ongoing support from trusted Microsoft partners like Zenzero.

Licensing and user considerations
Upgrading to Business Central also introduces a new licensing model. The transition from Microsoft Dynamics NAV to Business Central requires processing through the Microsoft License Transition program, which updates your license to the new Perpetual Dynamics 365 Business Central License – this is only available if you have an active Microsoft Enhancement plan. Existing Concurrent User licenses will be converted to Named User licenses at a 1:3 ratio, while recently purchased user licenses convert at a 1:1 ratio. If your business does not have an active Microsoft maintenance plan, you cannot transition your license and must purchase a new license – either as a capital purchase for on-premises or as a monthly subscription for cloud. Admins can set up users and assign licenses in the Microsoft 365 admin center.
Key considerations:
- Move from concurrent users to named users
- Review roles, permissions, and access levels
- Optimise licensing to control costs and maximise value
Planning early ensures no surprises during your license transition.
Common challenges (and how to overcome them)
While the benefits are clear, the journey from NAV to Business Central can present challenges:
- Complex custom code in older NAV versions
- Outdated data structures
- Integration with legacy systems
- Lack of internal team resources
Additionally, upgrade fees quoted by NAV partners can be substantial – often exceeding £100K – leaving many users frustrated and feeling pressured to pay these high costs just to move forward.
With the right support, these challenges can be effectively managed. At Zenzero, we use proven tools and methodologies to simplify even the most complex migration process.
