I am currently using iOS12 and I encountered some apps that no longer run in iOS12. Now, I want to transfer all obsolete iOS-apps I have on my iPhone to an old iPhone that can’t run iOS12.
How do I do that ?
The first step if you want to move apps from one iPhone/iPad to another iPad/iPhone, without using iTunes : start by backing up your obsolete apps to your Mac (or PC). Instructions can be found here.
Then, make sure you have an older iPhone/iPad that’s running iOS10 (or iOS9) ; the best would be a device that cannot run a newer version of iOS. Here’s a list of iOS-devices and the newest version of iOS they can run :
iOS-devices that can run iOS8 but not iOS9 (or tvOS9) : AppleTV 3
iOS-devices that can run iOS 9 but not iOS10 : iPhone 4s, iPod Touch 5, iPad 2, iPad 3 & iPad Mini 1
iOS-devices that can run iOS10 but not iOS11 : iPhone 5, iPhone 5c & iPad 4
Then, start transferring :
connect your ‘old’ iOS10 iPhone/iPad to your Mac using the usb-charging-cable.
then start the iMazing 2 software on your Mac
click on your ‘old’ iPhone/iPad’s icon in the list on the left
from the pulldown list, select Apps
from the bottom menu, click on “Copy to Device”
in the window that opens, select the folder that you have used to backup your (obsolete) iOS apps
select the apps you want to transfer and click “Select”
if you want to transfer any additional apps, repeat the process
when you have transferred all apps needed you can disconnect your iPhone/iPad from your Mac
now, find the transferred apps on your old iPhone/iPad and try if the app still runs on that iPhone
I have iOS12 running on my iPhone and I found that some the apps I have installed are no longer able to run on iOS12. I would like to delete these apps to save space on my iPhone, but I also want to make sure I have backup versions of all of them, because I might want to reinstall them in the future and Apple doesn’t guarantee that you will always be able to re-download all previous purchases (Apple will delete them from the AppStore when Apple judges the apps obsolete or inappropriate due to new regulations, even if I have payed to purchase them in the past).
How can I backup my incompatible apps ?
Technically, one would be able to backup all iPhone/iPad apps to iCloud wirelessly, or to iTunes on your Mac (or PC), but then you risk the app being deleted by Apple at any moment in the future, without warning and without compensation.
So, I would recommend using additional backup-/filetransfer-software on your Mac (or PC) to do so…at this moment iMazing 2 is a good option, but there are various alternatives around.
You can get iMazing 2 here. (the trial version is FREE)
And there currently is a discount version of iMazing 2 available here.
Here’s how to backup incompatible iOS apps :
on your iPhone/iPad go to Settings > General > About > Applications > Incompatible apps
make screen dumps (by pressing menu button & NO/OFF-button simultaneously) of the list of incompatible apps ; make multiple screen dumps if the list is very long
connect the iPhone/iPad to your Mac using a USB-cable
start the iMazing 2 app on your Mac (or use similar software)
click on your iPhone/iPad’s icon in the list on the left
from the pulldown list, select Apps
in the overview of installed iOS apps that shows up in the main screen, select the app that was listed first in the list of incompatible apps
then click the “Copy to Mac”-button
you will get a warning, telling you to make a full backup of your device ; do that first
when that’s finished, make sure that the first incompatible app is selected, then click “Copy to Mac” again
when asked where to save, select your desired save location and create a new folder and call it “incompatible apps iOS12” or something alike
then click OK
when done, select the second incompatible app and click “Copy to Mac”
save to the same “incompatible apps iOS12” folder
when asked, choose “Extract from current backup”
then repeat the saving process for all incompatible apps
when done, check if all incompatible apps you need are in the “incompatible apps iOS12” folder
if you missed one, back it up also
when done, select the first incompatible app again and click “Delete”
repeat that for all incompatible apps
in doing so, you will free up lots of valuable drive space on your iPhone/iPad
