But first, go here to learn about the differences between backing up with iCloud versus iTunes. If you don't feel like messing around with iExplorer or even Apple's iTunes backup service, you can always use iCloud. Let us know in the comments if you've used iExplorer or have any other suggestions to add. Most apps still save data locally though, meaning you can always use iExplorer if you prefer. It might be automatically doing that, or you need to turn on the feature in the app's settings. Just make sure the app is syncing to iCloud (more information here).
Some apps use iCloud, such as iA Writer, and in doing so, you have nothing to fret over. Not all apps save their files in the Documents folder, and in those instances, try copying the Library folder (which saves smaller high scores and other data) in addition to the Documents folder. Sometimes you might have two separate versions of an app (like an iPhone version and a HD iPad version), but you should still be able to transfer data between the two. The method should work for most apps, but just in case, here's some extra advice: You must remember that different apps use different save files, so you might have to adjust the above steps and copy several files or sometimes even just one file. There's a few things that can go wrong when using this method to transfer app and game data. Find the Documents folder for the app on your new device, and then copy all the data in the Documents folder on your desktop to the new device.
Disconnect your old device from your computer, then plug in your new device, and find the app you want to transfer data to on your new device using the same steps listed above. While inside the app's main folder, you'll see a folder called Documents (all of your app and game data should be located in Documents). From there, find the app you want to transfer data from, and then click the arrow. You'll then want to click the arrow next to your device name, followed by the arrow next to Apps. Your device should show up in the file browser. Plug your old device into your computer and launch iExplorer. So, if you want to transfer data from Minecraft, download the Minecraft app on your new device. Download the app you want to transfer data to on your new iOS device.
The idea is that you can transfer files from your device to your computer without having to sync everything. It not only works for apps but also music, voice memos, photos, SMS, etc. It's an app that facilitates the transfer of files from your iOS device to your computer, selectively, in order to create backups. But if you want to ensure that all your hard work in a particular game, such as Minecraft, is saved and moved to your new device, here's how to back up individual app data to your computer:
