Hi Ravi Singh,

You can develop the app in the regular way. The upgrade will not cause any issues. But I can provide some suggestion as you are on SOH.

1. Do not use the deprecated controls and keep a watch on the latest version of UI5 and see if any control gets depricated.

2. Better to upgrade to the latest version of the UI5 libraries if possible.

3. Use the smart controls for the Fiori app (Smart table, Smart table, Fiori element template based apps).

3. As your system has HANA DB, develop the Fiori apps based on the CDS views and use them as the source to show the UI.

4. In the OData service for F4 helps or for reports try to maps the CDS data source to entities so the SADL layer will take care of all the filtering, sorting, query parameters coming from the odata service (no need to handle manually). If you have option to use the odata service as referenced source that is even better.

5. If your system supports you can start developing the apps using the ABAP programming model for fiori (Non draft based apps have limitations though). Blog

There are many other ways to make use of HANA DB to improve the performance of the fiori app, you can find a lot of blogs on this topic.
