> Maybe I'm missing something, but don't the vast majority of applications don't care about what architecture they run on? There can be issues with moving to AArch64, for instance your Python code may depend on Python 'wheels' which in turn depend on C libraries that don't play nice with AArch64. I once encountered an issue like this, although I've now forgotten the details. If your software is pure Java I'd say the odds are pretty good that things will 'just work', but you'd still want to do testing.
