Last year when Windows Server 2019 was released I wanted to see which versions of SQL Server I could run on it, testing more the unwritten backward compatibility promise Microsoft has maintained over the last 45 years, rather than what the documentation says.
Speaking of documentation, Glenn Berry has a nifty compatibility matrix to show what versions of SQL Server are supported on each version of Windows Server. For official purposes, this is the list you should refer to:
But I know you’re not here for supported versions, because this post is about what Randolph managed to get running on Windows Server 2019, which as you know is a 64-bit operating system.
SQL Server 6.5 surprised me. This idea also nets my most coveted category.
