Is it possible to retain data of the older version if a new version of app is deployed on device?

I am new to iOS development so my question may be n00bish.I am working on an app for iPad which downloads PDFs and stores on the device(iPad) in the Documents directory so the user can still read them if he isn't connected to WiFi. My question is:if a newer version of the app is available and the user installs it, will it delete all the data(documents,in this case) from the device? If yes,how do I prevent the old data from being deleted? I am using CoreData in this app(if this helps)

When a user installs an updated version of any app, the app's sandbox is kept intact. Only the app and its resource bundle are replaced. So basically, anything you have stored in Documents or Library will be kept intact after the update process. There is no guarantee that files in Library/Caches or tmp will be kept but those should only have transient files anyway.
