Support policy

SQL Server follows the Fixed Lifecycle Policy: five years of Mainstream Support followed by five years of Extended Support. Paid Extended Security Updates (ESU) are then offered for up to three further years, and unlike Windows Server these ESU dates are published in advance.

Notes

SQL Server follows the Fixed Lifecycle Policy: five years of Mainstream Support plus five years of Extended Support — ten years in total, followed by up to three years of paid Extended Security Updates, for a maximum of thirteen.

During Extended Support only security updates are shipped; no new features and no non-security fixes.

Unlike Windows Server, SQL Server publishes its ESU dates in advance. Windows Server has not announced ESU availability for 2016 and later, but SQL Server 2014 and 2016 both carry a full three-year ESU schedule on Microsoft's lifecycle pages, so this site can show them as confirmed dates.

SQL Server 2016 needs attention now. Extended Support ended on 14 July 2026; without an ESU subscription it no longer receives security updates. ESU is sold per year and the price typically increases each year, so deferring migration compounds the cost.

Microsoft positions migration to Azure SQL Managed Instance or Azure Virtual Machines as the alternative to ESU, with ESU provided at no additional charge for workloads running on Azure. Whether you stay on-premises materially changes the real cost.

Dates do not differ between editions (Enterprise, Standard, Express, Developer). Microsoft publishes these dates in Pacific Time.
