Can I replace my old iPad with a new one?

Excuse me, I'm curious about something. I've been using my iPad for quite some time now, and it's starting to show its age. I've been eyeing the latest models and I'm wondering, is it possible to replace my old iPad with a new one? I'm not sure if there's a specific process or if I just need to go to an Apple store and make the swap. I'd appreciate any insight you can provide on this matter.
