Windows Server 2019 and .NET Framework 4.6.2 support

I have an ASP.NET Web Forms website built with .NET Framework 4.6.2.

Currently the website is published on IIS in a Windows Server 2012.

We have upgraded the server to Windows Server 2019 and the website is working without changing the framework version. But I know that .NET Framework version 4.6.2 cannot be installed on Windows Server 2019, so currently .NET 4.7 version is installed on the server. Please can you tell me if there is any contraindication to running an ASP.NET Web Site compiled with .NET Framework version 4.6.2 on Windows Server 2019?

    Depending on the actual .NET Framework version your Windows Server 2019 server has, you can find releases notes from Microsoft on what are the documented changes that might affect application compatibility,

    https://github.com/microsoft/dotnet/blob/main/releases/net47/dotnet47-changes.md

    Since each application can consume a unique API surface, it is impossible to tell which items might affect yours.

    The general recommendation is to develop a suite of regression test cases, so that once the migration to Windows Server 2019 finishes, your team can run it and identify the issues swiftly.
