Existing Fiori App Migration to HANA

Hi All,

I have deployed few Fiori transactional applications for customers .

Now,We are  planning to move on HANA database.

We need some info related to migration of existing apps to HANA database:

1. Can we directly use these transactional apps on HANA or do we need to do some configuration?

2. For customize Fiori application, do we have to do any modification(code changes in eclipse) from front end UI side.

3. Will there be any code changes on ODATA and Backend side.

Your help is highly appreciated.

Regards,

Dhiraj
