How to use mapping of struct in a upgradable contract? Where do i will define the struct and its mapping? On the storage contract or the logic contact. And how i am gonna push elements in mappings?

Mapping and structs are more of a storage thing...they don't have much to do with the logics that you are talking about

however, I guess you must specify a visibility in this mapping (public , private etc)..

As per the latest version of solidity, visibilities must be specified
