How was the data supposedly transferred from the old iPhone to the new iPhone?
I ask because the typical method is to backup the old iPhone and then use the back up of the old iPhone to setup/restore to the new iPhone. If that is the case, then is the backup (whether by way of iCloud or syncing with iTunes) still available?
If the backup is not available available anymore or some other method that did not involve backing up the iPhone to transfer the stuff was used, then you likely are out of luck. At that point, your only hope might be the person was at least using iCloud to sync things like calendars, contacts, Safari bookmarks, maybe photos (depending on settings), etc. Any apps, music, TV shows, movies, etc bought through the iTunes Store can be re-downloaded from either the App Store or the iTunes Store. And if any email accounts were setup, then if those email account were IMAP email accounts, then all the messages should be on the email service servers and it should just be a matter of re-setting up the email account(s). So, in theory (if using iCloud for syncing and have at least Photo Stream setup if not the full iCloud Photo Library turned on), then the things lost would be text messages, some system settings (i.e. WiFi networks remembered, Bluetooth devices remembered, passwords for things like iTunes/App Store and iMessage and Facetime, Privacy settings for various apps, etc), settings for most apps, and maybe some files/data for apps that store some stuff locally on the iPhone (i.e. say a PDF program, something like VLC with locally stored videos, etc) would be the only things truly lost. Of course, if they did not have iCloud setup (or something else that would sync things like contacts & calendars [such as Google], photos [like Dropbox], etc), then re-download apps and any iTunes purchased content.
