Transferring of Apps and Data

These support pages should get you started with setup of your new iPad - and the methods of transferring your data from old to new iPad:

Set up your iPhone, iPad or iPod touch – Apple Support

Transfer data from your previous iOS device to your new iPhone, iPad, or iPod touch - Apple Support

Use Quick Start to transfer data to a new iPhone, iPad or iPod touch – Apple Support

If the donor iPad, from which you are transferring your data precedes iOS12.4, QuickStart will not be available.

“Transfer” is rather a misnomer. In reality, your data and setup is merely cloned to the new device. Nothing is moved or removed from the original device.

An alternative is to restore either an iCloud or iTunes backup to the new device:

Apps are not actually “transferred”, but for App that remain available in the App Store, are automatically downloaded and installed from the Apple App Store.

Perhaps. Two possible issues come to mind, assuming there is no change in ownership and only your Apple ID is involved with owning everything.

1. Storage. You would certainly have issues if your replacement iPad has less storage than your original.
2. Aging. If you have not been keeping your apps updated and current, it’s possible some are no longer supported and are not in the App Store. These could not be placed on your new iPad.
