As of July 14, 2026, SQL Server 2016 is at the end of Microsoft’s extended support lifecycle. Under the Microsoft Lifecycle Policy, each SQL Server release gets 10 years of support. After that point:

• No regular security updates are released for SQL Server 2016.
• No standard technical support is provided by Microsoft for this version.

If you continue to run SQL Server 2016 without a transition plan, you increase:

• Security and compliance risk, especially for business-critical and regulated workloads.
• Exposure in an AI-accelerated threat landscape, where automated attacks can more easily target unsupported systems over time.

The recommended next step is to assess your current environment—including application dependencies, business criticality, performance needs, and readiness to modernize—and use that assessment to choose a path forward (cloud migration, upgrade, or temporary Extended Security Updates).

Microsoft outlines three main paths for organizations still on SQL Server 2016. Each is designed to keep you protected while you modernize:

1. Move to Azure SQL
   Modernize your data platform using Azure SQL services so you can reduce operational overhead and avoid recurring upgrade cycles.
   • Azure SQL Database: A managed database service for modern apps. The Hyperscale tier lets you scale compute and storage independently as your data grows.
   • Azure SQL Managed Instance: A SQL Server–compatible PaaS option that supports most existing workloads with minimal changes.
   • SQL Server on Azure Virtual Machines: Run SQL Server in Azure with full control over the OS, instance, and custom configurations.
   Azure SQL handles patching, backups, high availability, and version updates, so your team can focus more on delivering value than on infrastructure.
2. Upgrade to SQL Server 2025
   Stay on a supported platform while keeping your databases on-premises or in a hybrid setup. SQL Server 2025 brings:
   • Engine and performance improvements across query processing, indexing, and concurrency.
   • Ongoing investments in security, encryption, and compliance support.
   • Built-in AI capabilities, including vector search and semantic workflows, so you can build AI-driven apps directly on operational data.
   • Integration with Microsoft Fabric for mirroring operational data into analytics environments for near real-time insights.
   This is a good fit if you need tight control over performance and infrastructure.
3. Deploy Extended Security Updates (ESU)
   Use ESUs as a short-term bridge to maintain security coverage for SQL Server 2016 while you plan and execute your migration or upgrade.
   • Available for workloads in Azure (including SQL Server on Azure VMs and Azure VMware Solution) and for on-premises or multi-cloud via Azure Arc.
   • Offered as a paid program to extend security coverage beyond end of support.
   • Best suited for environments with complex dependencies, testing needs, or migration constraints.
   ESUs are intended as temporary protection while you move to Azure SQL or SQL Server 2025.

Many organizations are already taking these steps. For example, the Mediterranean Shipping Company (MSC) upgraded to SQL Server 2025 to modernize its deployment and streamline how operational data flows into Microsoft Fabric, enabling faster analytics and data-driven decisions across global operations.

You can think about the three options in terms of operating model, timing, and modernization goals:

1. Choose Azure SQL if you want to reimagine operations in the cloud

• You want to reduce maintenance (patching, backups, high availability) and avoid future upgrade cycles.
• You’re comfortable with a managed platform-as-a-service (PaaS) model.
• You want built-in resiliency, scalability, and security features, with strong backward compatibility for most SQL Server 2016 workloads.
• You may use tools like GitHub Copilot to help accelerate code changes during migration.

Within Azure SQL:

• Azure SQL Database: Best if you don’t need instance-level features and prefer an app-focused, elastic model.
• Azure SQL Managed Instance: Best if you want the closest PaaS experience to SQL Server with minimal application changes.
• SQL Server on Azure VMs: Best if you need full instance and OS control or rely on specific versions and third-party components.

You can also offset migration costs with Microsoft-funded delivery support, Azure credits, and investment programs.

2. Choose SQL Server 2025 if you want to modernize in place

• You plan to keep workloads on-premises or in a hybrid environment.
• You need tight control over performance, configuration, and infrastructure.
• You want to prepare for AI-driven scenarios while staying on SQL Server.

SQL Server 2025 gives you:

• Engine and performance improvements for high-volume transactional workloads.
• Enhanced security and data protection aligned with regulated environments.
• Built-in AI features like vector search and semantic workflows.
• Integration with Microsoft Fabric for near real-time analytics on mirrored operational data.

3. Choose Extended Security Updates if you need more time

• You can’t move off SQL Server 2016 immediately due to application dependencies, testing requirements, or migration complexity.
• You need to maintain security coverage while you plan and execute a transition.
• You understand ESUs are a temporary bridge, not a long-term strategy.

ESUs are available for Azure, on-premises, and multi-cloud environments (via Azure Arc) as a paid program, and are intended to keep you protected while you move to Azure SQL or SQL Server 2025.

In practice, many organizations use a combination of these paths—for example, moving some workloads to Azure SQL, upgrading others to SQL Server 2025, and using ESUs only where extra time is needed. A structured assessment of your applications, criticality, and modernization readiness will help you map each workload to the right option.
