For various reasons beyond the scope of this post, I must create a new Apple ID and iTunes account. There are a few apps on my phone that I must preserve the content from (I don't mind re-buying the app).
This post from 2013 indicated that I could backup the app .ipa file to my computer, retrieve the 'container' folder, and then restore it to the filesystem once installing the app under my new account.
However, the desktop applications used in that post don't seem to function properly with ios11 and I'm unable to access the filesystem to restore content.
- Is there another clever way to do this?
- If I switch accounts and try to re-install the app, will it locate the old data?
