I can’t sync my new Samsung tab A tablet to my older Samsung tablet in order to be able to keep all my pictures etc.

For pictures, make sure that you have the “Photos” app installed, (looks like a little multi-colored wind mill) then open it, and go through setup. The photos will automatically back up to there and you can use this app on your new tablet to view them. What else do you want on your new tablet?
