I have several older apps that are no longer offered in the app store. I am considering upgrading to iOS 11, but I am concerned that I will be unable to recover those apps should they be deleted from my iPhone (or should I lose it).
Many of these apps, of course, are not 64-bit compatible, and therefore will never run under iOS 11 or later anyway. But of course apps vanish from the app store all the time, and I'm wondering whether the massive archive of iOS apps I have sitting on my hard drive becomes useless when I upgrade to iOS 11.
I realize that iTunes 12.7 removes this capability, but I was hoping that I could just stay with 12.6, or, ideally, open 12.6 when I needed, even though 12.7 is installed.
So my question is: Is it possible to use iTunes 12.6 to load apps from my hard drive onto an iOS 11 device?
