iCloud backup on ipad

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:

An iCloud backup will contain all locally stored data that has not already been synchronised with iCloud. Between the backup and iCloud, all locally stored data will be included within the backup - unless you have intentionally and explicitly deselected specific elements from the backup:

Settings > [Your Name / AppleID] > iCloud > Manage Account Storage > Backups > [This iPad] Show All Apps

Here you can see all the Apps whose data will be included or excluded from the iCloud backup.

As for Apps themselves, these are not directly transferred between devices. For Apps, the transfer process creates a record of the Apps that are installed on the donor iPad - and it is this record of installed Apps that is transferred to the target (new) device. For Apps that are still available for download from the App Store, the corresponding Apps are automatically downloaded and installed from the App Store. The Apps will be associated with the corresponding App data included within the backup.
