SQL Server 2016 End of Support: What Companies Should Review Now

This article covers the upcoming end of extended support for SQL Server 2016 on July 14, 2026, and the implications for organizations still using it. It explains that after this date, regular security updates stop unless companies opt for Extended Security Updates (ESU). The article emphasizes that the real challenge is not just the calendar milestone but the operational maturity, legacy dependencies, incomplete documentation, and technical debt that accumulate over time. It advises against complacency, noting that 'it still works' is not a strategy, and highlights risks like security exposure, audit difficulties, and vendor support boundaries. It calls for thorough inventory, dependency mapping, and realistic upgrade or migration planning to avoid urgent decision-making under pressure.
