Information about Standard iviews in FIORI

Hi Experts,

My requirement is that, some standard iviews are running in my company and I want to move to FIORI.

So is it possible that without changing anything can i configure and run the FIORI applications ?

And also some custom Ivews and custom ABAP programs are running for other applications.

So how can I configure these applications in fiori ?

Please see the below screen shot for standard iviews in HCM .

Thanks and Regards,
