Currently, to deploy our enterprise app, we get the client to download the latest app build bundle and install it using the iPhone Configuration Utility. Unfortunately when they uninstall the current build of the app, it removes all its related files on the device. They need to uninstall the app before being able to install the new build of the app.
Is there a way to update to the new build while retaining some of the existing files on the device so that the entire app isn't completely reset (e.g. logging and setting files)?
There doesn't seem to be an update enterprise app mechanism unlike the regular app store, or have I missed a feature somewhere?
