I know the .NET story much better than Java. .NET Framework support is tied to the OS support for one thing, so as long as Windows is supported, so is the corollary.NET version.
One of the values of .NET Core is that it doesn't need to be installed at all in the OS.
We are migrating away from. NET as a SaaS company. Our Monolith is in Framework and being deconstructed into .NET (current) services. It's a journey, hoping to be done in 2 years. We did successfully migrate the frontend from webforms to React, page by page. I'm sure there are other teams as well. I just interviewed a lead that was on a team doing the same thing on a Java 8 platform with a monolith.
