old iPad transfer photos etc.. to new iPad

If you're using iCloud Photos on the old iPad, and set up the new iPad to use iCloud Photos and the same Apple ID, the photos in iCloud Photos should appear on your new iPad. (If you have a lot of photos, synchronization might take a while.)

If your old iPad is not using iCloud Photos (and you don't want to turn it on), you could use Image Capture to pull its photos to your Mac.

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:

Many Apps and services may be synchronised with iCloud - and for those that are, all will synchronised between devices that are signed-in to iCloud with the same AppleID:

Settings > [Your Name / AppleID] > iCloud - enable Apps and services to synchronise via iCloud as required
