SQL Server 2025’s 1% adoption rate might sound small, but it mirrors the adoption rate curves of 2019 and 2022 when those releases came out. It took 2019 a year to break 10% adoption, and it took 2022 a year and a half. I’ve grouped together 2014 & prior versions because they’re all unsupported, and 2016 will join them quickly in July when it goes out of extended support. (I can’t believe it’s been almost 10 years already!) Here’s how adoption is trending over time, with the most recent data at the right:
