Late to the thread, but just to chime in, briefly - I would agree unless the underlying platform has been deprecated. If we're talking about something in Java that could be better, in the abstract, but it still works, agreed: it might not be worth the effort to redo. Java isn't going anywhere, and versioning differences aren't always critical. If we're talking about deprecated front end frameworks that no longer have any LTS (Angular 1 comes to mind), moving over to a framework that does have LTS is a pretty smart move, if the code or app is that important and valuable.
