How should iOS app data files for new app version be moved from NSDocumentDirectory to NSLibraryDirectory?
<p>In the current version of my app, I have stored two important app files (my Core Data .sqlite file and my SettingsFile.plist) in the NSDocumentDirectory. In the next version, I want to move these files to the NSLibraryDirectory. Neither needs to be directly accessed by the user for editing, and it seems from my research that this is the best option for each of these files.</p>

<p>I am concerned with how to move the files for all of my current app users from the NSDocumentDirectory to the NSLibraryDirectory. I want to be very careful not to lose any of the users' data. I don't know where or how to begin to go about moving these files in a very safe way. I am hoping someone can point me in the right direction.</p>
