Windows Server 2016, .NET Framework 4.6.2, IIS 10 on 2016, BizTalk 2016, System Center 2016 and TFS 2017 all end support in January 2027. SQL Server 2017 follows in October, after SQL Server 2016, SharePoint 2016 and 2019 and .NET 8 in 2026. The full list for server teams, and what each ending actually means.
When a Microsoft product reaches end of support there are no more security updates, no non-security fixes and no paid support, unless you buy Extended Security Updates where they are offered. The software keeps running. The risk is everything discovered after that date.

Most companies we talk to underestimate January 2027, because it is not one product. A typical line-of-business application from 2016 runs on Windows Server 2016, IIS 10, .NET Framework 4.6.2, talks to SQL Server 2016 or 2017, is integrated through BizTalk 2016, monitored by System Center 2016 and built in TFS 2017. Every layer of that stack reaches end of support within about nine months.
Upgrade in place to the current version. Fastest, keeps the architecture, resets the clock for five to ten years.
Buy Extended Security Updates where offered (Windows Server 2016 ESUs are sold through Azure Arc, which can manage servers outside Azure, including on AWS). Buys time, at a price that rises each year.
Move to a managed service, such as RDS for SQL Server or Microsoft 365 for SharePoint and Exchange, so version upgrades become someone else's scheduled job.
Modernize: .NET Framework to modern .NET on Linux, SQL Server to PostgreSQL, BizTalk to cloud integration services. Most work, and it removes licence cost along with the deadline.
Retire it. Every end-of-support list contains applications nobody uses. Check usage before you spend anything.
Once a month: what changed in tech that month and what it means for you, from cloud and AI to security and the tools you build with. Every item links to its source. No sales pitch, unsubscribe in one click.

SQL Server 2016 Has Ended and 2017 Ends October 2027: Upgrade, Move to RDS, or Leave for PostgreSQL
SQL Server 2016 reached end of support on July 14, 2026; SQL Server 2017 follows on October 12, 2027, and SQL Server 2014's last ESUs end in July 2027. The three realistic paths on AWS (a newer SQL Server on EC2 or RDS, Aurora PostgreSQL with Babelfish, or a full conversion with AWS Transform) and what each costs in licences and effort.
