Question

Also what are all the changes required in web.config file of Prover hosted app while migrating it to SharePoint Online?

Answer 1

You have file system in Azure Web app and you can write to it. The only important thing is, that you can't rely on a file system as a permanent storage for your files. As per comments, D:\home is persisted. You can write to this directory and data should be persisted across all instances and never deleted.

Additionally, for permanent file storage solution you can use other things provided by Azure:
Azure blob storage
