Is there anyone, who has experienced issues (compatibility, performance) i relation to upgrading to .NET Framework 4.7, and from which version?
Not sure if you looked at the Sitecore compatibility table? URL: https://kb.sitecore.net/articles/087164
I know this does not answer your question directly however some pointer for you to know which .NET version is compatible with sitecore versions.
Hope this helps.
