SQL Server 2016 End of Support: Upgrade & Migration

SQL Server 2016 end of support

SQL Server 2016 support has ended. What’s your plan?

Microsoft ended extended support for SQL Server 2016 on July 14, 2026. Without a plan, your databases no longer receive regular security updates or Microsoft technical support. We help you decide, quickly and with evidence, whether to upgrade in place, migrate to Azure or AWS, or consolidate, and what it will cost.

What end of support means for you

  • No regular security updates. New vulnerabilities in SQL Server 2016 are no longer patched unless you pay for Extended Security Updates.
  • No standard Microsoft support. When something breaks, there is no routine support path.
  • Audit and compliance pressure. Unsupported database software is a common finding in HIPAA, PCI and SOC reviews and in cyber-insurance questionnaires.
  • Vendor compatibility. Application vendors increasingly certify only supported SQL Server versions.

And SQL Server 2016 is not the only version to watch: anything before SQL Server 2022 is already out of mainstream support, and extended support for SQL Server 2017 ends on October 12, 2027.

Your options

  1. Buy time with Extended Security Updates. Paid ESUs deliver critical security updates for up to three years. They are a bridge, not a destination.
  2. Upgrade in place or side by side. Move to SQL Server 2022 or 2025 on your own infrastructure, with compatibility testing and a rollback plan.
  3. Migrate to the cloud. Azure SQL Managed Instance, SQL Server on Azure VMs, or AWS, chosen for your workloads, not by default.
  4. Consolidate while you move. An upgrade is the best moment to reduce instance sprawl and licensing cost.

Upgrade & Migration Readiness Assessment

A fixed-scope engagement that gives you a decision-ready plan:

  • Inventory: the SQL Server instances found, with version, edition and the databases and applications that depend on them.
  • Compatibility review: features, deprecated functionality and application vendor requirements that affect the target version or platform.
  • Target options compared: in-place upgrade vs. Azure vs. AWS vs. consolidation, with risk, effort and cost for each.
  • Licensing and consolidation: where you can run fewer instances, cores or licenses after the move.
  • High availability design: the right HA and disaster recovery architecture for the new platform.
  • Security baseline: find permission and configuration risks before you move, so they don’t follow you onto the new platform.
  • Roadmap: a prioritized, phased plan with effort estimates your team or ours can execute.
