For businesses that rely on Microsoft’s legacy ERP systems, the "future of on-premise" is no longer a distant discussion—it is a current reality. While much of the recent industry attention has focused on the immediate Dynamics CRM 2016 end of life date (January 13, 2026), a secondary and equally critical wave is hitting the ERP sector.
As of early 2026, thousands of organizations are preparing for the Dynamics NAV 2016 end of support, which is scheduled for April 14, 2026. With only three months remaining until this deadline, the window for a structured, non-disruptive transition to Business Central is rapidly closing. This post explores the shifting landscape of Microsoft’s ERP portfolio and helps you decide the best path forward for your financial data.
1. The Countdown to April 2026: Dynamics NAV 2016 Support End
Dynamics NAV 2016 (version 9.0) has been a workhorse for mid-market manufacturing, distribution, and professional services for over a decade. However, under the Microsoft Fixed Lifecycle Policy, its ten-year journey is coming to an end.
Key Deadlines to Watch:
- Dynamics NAV 2015: Extended support expired on January 14, 2025.
- Dynamics NAV 2016: Extended support ends on April 14, 2026.
- Dynamics NAV 2017: Extended support ends on January 11, 2027.
If your business is currently running NAV 2016, you are currently in the final 90 days of receiving security updates. After April 14th, your ERP—the very heart of your financial and inventory management—will no longer receive "year-end" updates, tax table adjustments, or critical security patches.

2. Is Dynamics 365 Finance and Operations On-Premises Support Ending Soon?
While NAV users face a version-specific deadline, users of larger enterprise systems are asking: "Is Dynamics 365 Finance and Operations (F&O) on-premises support ending soon?"
The answer is less about a single "end date" and more about a fundamental shift in licensing and enforcement. As of January 15, 2026, Microsoft is beginning a staged rollout of per-user license validation for all Finance and Operations customers.
For on-premises F&O users, this means that the "honors system" of the past is being replaced by active, in-product enforcement. If your on-premises environment is not synced with your Microsoft 365 Admin Center for license verification, users may begin seeing in-app warnings or experience blocked access starting this month. While support for F&O on-premises continues via the "One Version" service update model, the infrastructure requirements and licensing compliance are becoming increasingly aligned with cloud standards.
3. The Big Question: Business Central or Dynamics 365 Sales from CRM 2016?
For organizations currently facing the Dynamics CRM 2016 end of life, there is often confusion regarding which modern application to adopt. Many look at the integrated nature of Microsoft’s modern stack and ask: "Should I move to Business Central or Dynamics 365 Sales from CRM 2016?"
The Decision Matrix:
- Move to Dynamics 365 Sales (Online) if your primary goal is to replace your existing CRM 2016 functionality. This is the direct successor and offers the most familiar experience for your sales and service teams, now enhanced with AI-driven conversation intelligence.
- Move to Business Central if you are looking to consolidate your systems. Business Central is a "Cloud ERP" that includes basic Relationship Management (CRM) features. If your CRM needs are simple—tracking contacts, basic quotes, and interactions—Business Central can act as both your accounting system and your CRM, eliminating the need for two separate licenses.
- The Hybrid Approach: Most growing enterprises choose to integrate both. You can run Business Central for your "back-office" (Finance/Inventory) and Dynamics 365 Sales for your "front-office" (High-velocity sales), thanks to the native, pre-built integration between the two platforms.
4. Does Microsoft Force Cloud Migration for Dynamics?
One of the most pervasive myths in the IT community is that Microsoft forces cloud migration. From a technical standpoint, this is false. Microsoft still allows for on-premises deployments of Business Central and Finance & Operations.
However, from a policy and innovation standpoint, the push is undeniable.
- Innovation Lock-out: New features, such as Microsoft Copilot for ERP, are built on the Power Platform and require cloud connectivity. On-premises users are effectively locked out of the AI revolution.
- Financial Incentives: The "Bridge to the Cloud-2" promotion offers existing on-premises customers a massive discount (often 40% or more) to transition to cloud licensing while retaining their on-premises rights during the move.
- The Maintenance Burden: As security standards like TLS 1.3 become mandatory, maintaining an on-premises server that can securely communicate with modern banking or shipping APIs is becoming prohibitively expensive for most IT departments.
5. The Dynamics On-Premise Future: What Lies Beyond 2026?
What is the dynamics on-prem future? Looking toward 2027 and 2028, it is clear that "On-Premise" is becoming a niche deployment option reserved only for organizations with extreme regulatory requirements or zero internet connectivity (such as ships or remote mines).
For the average business, the "On-Premise" era is sunsetting because the underlying architecture of modern business—AI, real-time data streaming, and cross-platform collaboration—cannot be sustained on local hardware. The Dynamics CRM 2016 end of life date was the first major domino of 2026; the NAV 2016 deadline in April is the second.
6. Strategic Steps for NAV 2016 Users
If you are still on NAV 2016 as of January 2026, your "90-day plan" should include:
- C/AL to AL Code Assessment: Legacy NAV uses C/AL code, while Business Central uses AL extensions. You must determine how much of your "custom" logic needs to be rewritten versus replaced by modern out-of-the-box features.
- Data Archiving: ERP databases are often bloated with 10+ years of historical transactions. Use this migration as an opportunity to archive old data and move only "Clean Master Data" to the cloud.
- User Retraining: The "Web Client" of Business Central is a significant change from the "RoleTailored Client" of NAV 2016. Early exposure and training for your finance team are essential for a successful go-live.
