Selective transfer of apps across iPads
I have 2 iPads with an App on the old iPad that I want on the new iPad. I cannot download the app from the App Store as it says the App is no longer in the Store. Is there any way I can transfer the app from the old iPad to the new ipad? I have been using the new iPad for a few months so do not want to lose any apps or Data already on it.
iPad Pro 12.9-inch, 3rd Gen, Wi-Fi
