IOS – Transfer iOS app data to a different account

apple-idiosipad

I have an iPad 2 currently using my AppleID. I want to reset it
(almost) completely and change it to my girlfriend's Apple ID.

The thing is: there are 2 or 3 apps whose data we really don't want to
loose. They are free apps, so it's trivial to reinstall them under the
new account.

I only need a way of backing up the data of these apps under my Apple
ID and then restoring it under her Apple ID.

Is there a way to achieve this?

I'm not trying to transfer purchases or anything like that, just copy
some data.

NOTE: The software needs to be Windows or Linux.

You can backup data from apps with a program such as PhoneView (Mac) or iFunBox (Mac & Windows).

Browse, manage and download most any data saved by App Store apps from your iPhone, iPad or iPod Touch. If you're looking for a quick way to download saved recordings, videos or images from your apps, this is it. Even transfer game high scores between devices. --PhoneView

This data can then be restored to a new installation of an app under a different Apple ID or even on a different device.
