Dynamics NAV vs Dynamics 365 Business Central: Should You Upgrade?

If your company is currently running Microsoft Dynamics NAV, you may be asking an important question: Should we continue running Dynamics NAV, or upgrade to Dynamics 365 Business Central?

Dynamics NAV has been a reliable ERP platform for many years. Many organizations still rely on it to manage financials, inventory, operations, and reporting across the business.

However, Microsoft’s ERP strategy has shifted toward cloud-based Dynamics 365 applications, with Dynamics 365 Business Central positioned as the long-term platform for small and mid-sized businesses.

Because of this shift, many NAV customers are beginning to evaluate their options.

Some organizations want to reduce the effort required to maintain servers and manage ERP upgrades. Others are looking for improved accessibility, stronger reporting capabilities, and better integration with tools like Microsoft 365, Power BI, and Azure.

At the same time, upgrading from NAV is not always a simple decision. Many companies have invested years into customizing their NAV environment and building processes around it.

The real question is not simply whether Business Central is newer.

It is whether moving to Business Central will better support how your business wants to operate and grow.

In this guide, we compare the pros and cons of upgrading from Dynamics NAV to Dynamics 365 Business Central, including:

• Infrastructure and deployment differences
• Customizations and extension considerations
• Cost and upgrade effort
• Functional advantages of Business Central

Understanding these factors will help you determine whether upgrading to Business Central is the right next step for your organization.

Quick Overview: Dynamics NAV vs Dynamics 365 Business Central

The main difference between Dynamics NAV and Dynamics 365 Business Central is how the systems are delivered, maintained, and extended.

Dynamics NAV was traditionally deployed on-premises or through hosted infrastructure, which means the organization is responsible for managing servers, updates, backups, and security.

Dynamics 365 Business Central, by contrast, is designed as a cloud-based SaaS ERP platform hosted on Microsoft Azure. Microsoft manages the infrastructure, updates, and security while organizations access the system through a browser or mobile device.

Because of this shift, the day-to-day experience of running the system can be very different.

Organizations running Dynamics NAV often spend time managing:

• server infrastructure
• upgrade planning and testing
• system maintenance
• backup and disaster recovery

With Business Central, many of these responsibilities are handled by Microsoft through the cloud platform.

That difference affects several important areas, including:

• how the system is licensed
• how upgrades are delivered
• how third-party functionality is added
• how easily the system integrates with other Microsoft tools

At a high level, both systems support the core ERP functions most businesses rely on, including financial management, purchasing, inventory tracking, and operational reporting.

The bigger difference is how much time, effort, and internal IT support are required to keep the system running and up to date.

The table below highlights some of the most important differences between Dynamics NAV and Business Central.

For many organizations, the decision is not just about choosing between an older ERP system and a newer one.

It is about deciding whether to continue maintaining a legacy environment or move to a modern platform that reduces infrastructure demands, simplifies upgrades, and supports long-term growth.

Understanding that difference helps frame the rest of the discussion around whether upgrading from Dynamics NAV to Business Central makes sense for your business.

Licensing and Hosting

One of the biggest differences between Dynamics NAV and Dynamics 365 Business Central is how the systems are licensed and hosted.

These differences affect several practical considerations for your business, including:

• upfront software costs
• ongoing IT responsibilities
• upgrade requirements
• long-term system maintenance

Understanding how each ERP system is delivered can help clarify what running the system will look like day to day.

Dynamics NAV Licensing and Hosting

Dynamics NAV has traditionally been sold through a perpetual licensing model.

Companies purchase the software upfront and then pay an annual maintenance fee for updates and support.

In addition to the software license, organizations are typically responsible for the infrastructure required to run the system.

Dynamics NAV environments are usually deployed in one of two ways.

On-Premises Deployment

Many companies run Dynamics NAV on servers within their own environment. This model gives organizations a high level of control over how the system is configured and secured.

However, it also means the company is responsible for maintaining the underlying infrastructure, including:

• server hardware
• system backups and disaster recovery
• security management
• system upgrades and testing

For organizations with dedicated IT resources, this level of control can be valuable. But it also requires ongoing time and operational effort.

Hosted Dynamics NAV (Infrastructure-as-a-Service)

Some organizations host Dynamics NAV through a third-party cloud infrastructure provider.

This approach removes the need to maintain physical servers internally, but it does not convert NAV into a true SaaS platform.

The organization still manages the application itself, including:

• system upgrades
• environment configuration
• application maintenance

Pros of Dynamics NAV Licensing and Hosting

• perpetual licensing option
• concurrent user licensing model
• full control over system infrastructure

Cons

• ongoing infrastructure responsibilities
• manual upgrades and testing
• higher long-term IT maintenance requirements

Business Central Licensing and Hosting

Dynamics 365 Business Central uses a different delivery model.

Business Central is primarily delivered as a Software-as-a-Service (SaaS) ERP system hosted on Microsoft Azure.

Instead of purchasing the software outright, companies license Business Central through a per-user subscription model.

Because Microsoft manages the cloud infrastructure, many of the technical responsibilities associated with running ERP software are handled automatically.

This includes:

• automatic updates and feature releases
• built-in security and compliance controls
• system backups and disaster recovery
• global accessibility through a web browser or mobile device

For many organizations, this significantly reduces the internal IT effort required to keep their ERP systems secure, up to date, and available to users.

Business Central uses named-user licensing, meaning each user receives their own license based on their role and level of system access.

Pros of Business Central Licensing and Hosting

• automatic updates and feature enhancements
• no internal server infrastructure required
• built-in security and backup management
• easier remote and mobile access

Cons

• named user licensing structure
• less flexibility for organizations accustomed to concurrent licensing

Licensing and Hosting Summary

Both Dynamics NAV and Business Central support the core ERP needs of small and mid-sized organizations.

The main difference is how much responsibility your organization wants to take on for maintaining the system.

Dynamics NAV provides greater control over infrastructure and deployment, but it also requires more ongoing management, upgrade planning, and IT involvement.

Business Central shifts much of that responsibility to Microsoft through its cloud-based architecture. For many organizations, this reduces infrastructure complexity and allows internal teams to focus more on business operations instead of system maintenance.

For companies evaluating an upgrade, this difference in infrastructure responsibility is often one of the most important factors in the decision.

Because Business Central uses a subscription-based licensing model, many organizations also evaluate how user licensing and implementation costs will affect their long-term ERP investment.

Our Microsoft Dynamics 365 Business Central Pricing Guide explains how licensing works and what companies should expect when planning a migration.

Customizations and Extensions

Another important difference between Dynamics NAV and Dynamics 365 Business Central is how each platform handles customizations and third-party functionality.

Most ERP systems need to be tailored to fit in with how a company operates. This might include industry-specific workflows, specialized reporting, warehouse automation, manufacturing tools, or integrations with other business systems.

The way these customizations are developed and maintained can significantly affect how easy it is to upgrade, extend, and maintain the system over time.

Dynamics NAV Customizations

Dynamics NAV has long been known for its flexibility. Over the years, many organizations customized the system to support their unique processes.

These customizations were typically built directly into the core application using Microsoft’s development environment.

This approach allowed partners and developers to modify NAV in powerful ways, but it also created challenges when it came time to upgrade.

Because customizations were embedded in the core system, upgrades often required additional work to:

• review existing custom code
• adjust modifications to match the new version
• test integrations and reporting

For organizations with heavily customized environments, upgrades can become large projects requiring careful planning and testing.

In some cases, the time and cost of reworking customizations have caused organizations to delay upgrades longer than planned.

Pros of NAV Customizations

• highly flexible development model
• strong ability to tailor the system to specific business processes
• many long-standing custom solutions already in place

Cons

• custom code may complicate upgrades
• modifications may require rework during system updates
• environments can become harder to maintain over time
  
  

Business Central Extensions

Dynamics 365 Business Central approaches customization differently.

Instead of modifying the core system directly, Business Central uses a modern extension framework. Extensions allow partners and developers to add functionality to the platform without changing the underlying application code.

Most extensions are distributed through Microsoft AppSource, a marketplace where organizations can discover and install apps built for the Microsoft ecosystem.

This architecture provides several advantages.

Extensions can be installed, updated, and removed independently from the core system. Because they do not modify the base application, Microsoft can deliver platform updates without requiring the same level of redevelopment as older customization models sometimes did.

For many organizations, this makes it easier to keep the ERP system current without turning every update into a large upgrade project.

It also allows companies to expand functionality over time by adding specialized apps as their operational needs evolve.

Pros of Business Central Extensions

• modern extension framework designed for cloud ERP
• growing ecosystem of apps available through Microsoft AppSource
• extensions update alongside the core platform
• easier long-term upgrade and maintenance management

Cons

• some legacy NAV customizations may need to be redesigned as extensions
• certain niche solutions may require new development

Customizations and Extensions Summary

Both Dynamics NAV and Business Central allow organizations to tailor their ERP systems to match their operational needs.

The key difference lies in how those customizations are managed over time.

Dynamics NAV environments often rely on embedded custom code, which can make upgrades more involved and time-consuming.

Business Central uses an extension model designed for modern cloud platforms, allowing functionality to be added or updated without modifying the core system.

For many organizations planning their long-term ERP strategy, this shift makes it easier to maintain the system, stay current with updates, and continue expanding capabilities as the business grows.

Functionality and Integrations

Beyond licensing and customizations, another important area to compare is core functionality and system integrations.

Both Dynamics NAV and Dynamics 365 Business Central provide the core ERP capabilities most small and mid-sized organizations need. These typically include financial management, purchasing, inventory tracking, and operational reporting.

However, there are differences in how these capabilities are delivered and how easily each system connects with other business tools.

Dynamics NAV Functionality and Integrations

Core capabilities typically include:

• General ledger and financial management
• Accounts payable and receivable
• Fixed assets management
• Inventory tracking and purchasing
• Multi-currency and multi-company support
• Sales order and purchase order management

These capabilities allow organizations to manage many business processes within a single ERP system.

However, in many NAV environments, certain capabilities rely on additional tools or integrations.

For example:

• advanced reporting may use tools like Jet Reports
• analytics dashboards may require separate configuration
• integrations with other Microsoft products may require additional setup

These solutions can work well, but they often mean reporting, analytics, and integrations are managed across multiple tools instead of within a single connected platform.

Pros of Dynamics NAV Functionality

• mature financial management capabilities
• highly customizable operational workflows
• proven functionality used by organizations for many years

Cons

• some modern reporting and analytics tools require additional setup
• integrations may require custom configuration
• new functionality may depend on third-party solutions

Business Central Functionality and Integrations

Dynamics 365 Business Central delivers many of the same core ERP capabilities as Dynamics NAV, but it was designed as part of Microsoft’s modern cloud ecosystem.

As a Business Central business management solution, it helps organizations manage finance, inventory, sales, and operations in one connected platform.

Core functionality includes:

• financial management and general ledger
• accounts payable and receivable
• inventory and warehouse management
• purchasing and sales order processing

• Microsoft 365 tools like Excel and Outlook integrate directly with ERP data
• Dynamics 365 applications can extend CRM and service capabilities

Because Business Central is cloud-based, these integrations are typically easier to configure and maintain.

For many organizations, this creates a more connected environment where financial data, operational insights, and collaboration tools work together. Leadership teams gain clearer visibility across departments without relying on multiple disconnected systems.

Pros of Business Central Functionality

• strong financial and operational capabilities
• built-in automation and forecasting tools
• easier integration with Microsoft products
• modern analytics and reporting capabilities

Cons

• payroll often requires a third-party application
• some specialized workflows may require extensions

Functionality and Integrations Summary

Both Dynamics NAV and Business Central provide the core ERP tools most organizations need to manage financials, purchasing, inventory, and operations.

The main difference lies in how easily those capabilities connect with modern reporting tools and other business applications.

Dynamics NAV environments often rely on integrations and reporting tools that have been added over time.

Business Central was designed to integrate more naturally with the broader Microsoft ecosystem, making it easier to connect ERP data with analytics, collaboration tools, and other cloud services.

For many companies evaluating their ERP future, the decision ultimately comes down to whether their current environment provides the level of connectivity, visibility, and automation they need to support continued growth.

Pros and Cons of Upgrading from Dynamics NAV to Business Central

After reviewing the differences in licensing, customizations, and functionality, many organizations reach the next logical question:

Does it make sense to upgrade from Dynamics NAV to Business Central?

For many companies, the answer depends on how well their current system supports their operational needs today and how prepared they are for future growth.

Business Central introduces modern cloud capabilities, but upgrading from a long-standing NAV environment can require planning, especially if the system includes customizations or specialized integrations.

Understanding both the advantages and potential challenges can help organizations evaluate whether the upgrade is the right move.

Advantages of Upgrading to Business Central

For many Dynamics NAV customers, the biggest advantages of upgrading come from the shift to a modern cloud-based platform.

1. Access from Anywhere

Because Business Central is delivered through the cloud, users can access the system from a web browser or mobile device with an internet connection.

This cloud architecture allows organizations to work from anywhere while maintaining centralized financial and operational data within the Dynamics 365 Business Central cloud ERP platform.

This flexibility allows employees to work from multiple locations without relying on VPN connections or remote desktop environments.

For organizations with distributed teams or multiple locations, this can improve collaboration and allow decision-makers to access real-time data wherever they work.

2. Reduced Infrastructure Management

Running NAV on-premises typically requires internal resources to maintain servers, backups, and security controls.

With Business Central, Microsoft manages the infrastructure through Microsoft Azure.

This shifts much of the technical responsibility away from internal IT teams and reduces the effort required to maintain the ERP environment.

3. Automatic Updates

Traditional NAV environments require organizations to plan and execute upgrade projects when new versions are released.

Business Central uses a continuous update model where Microsoft delivers improvements and security updates automatically.

This helps organizations stay current without large upgrade projects and reduces the risk of falling behind on supported versions.

4. Stronger Integration with Microsoft Tools

Business Central integrates directly with the broader Microsoft ecosystem.

Organizations can connect ERP data with tools such as:

• Power BI for reporting and analytics
• Microsoft 365 for productivity and collaboration
• Dynamics 365 applications for CRM and service management

These integrations help organizations create a more connected environment where financial data, operational insights, and collaboration tools work together.

Potential Challenges to Consider

While Business Central provides many advantages, upgrading from NAV still requires thoughtful planning.

Organizations should be aware of several common considerations.

1. Customization Migration

Many NAV systems include custom modifications built directly into the application.

When moving to Business Central, these customizations may need to be redesigned using the extension framework.

Depending on the complexity of the existing environment, this can add time and effort to the upgrade process.

2. Change Management and Training

Even though Business Central is built on the same foundation as NAV, the user experience and workflows may differ.

Employees may need training to become comfortable with the updated interface and new capabilities.

Organizations that plan for user adoption early typically experience smoother transitions.

3. Implementation Planning

An upgrade to Business Central is not just a technical project. It is also an opportunity to review business processes and system configuration.

Many organizations take this opportunity to streamline workflows, improve reporting structures, and strengthen data management practices. While this planning adds effort during the implementation phase, it can also create long-term operational benefits.

Moving to a cloud ERP platform often changes how teams manage updates, governance, and system ownership. Our article on cloud ERP strategy and what changes Monday morning explores the operational shifts many organizations experience after moving to the cloud.

Many of the challenges organizations encounter during ERP modernization stem from planning assumptions rather than software limitations. In our guide to Business Central cloud implementation mistakes, we discuss the governance and planning issues that often create friction after go-live.

Upgrade Decision Summary

For many Dynamics NAV customers, the decision to upgrade is less about replacing a system that no longer works and more about preparing for the future.

Dynamics NAV can still support many organizations today. However, Business Central introduces capabilities designed for modern cloud environments, including automatic updates, easier integrations, and reduced infrastructure management.

The real question is not simply whether NAV still works.

It is whether your current ERP environment provides the flexibility, visibility, and scalability your business will need going forward.
