New iPads as in the 5th or 6th gen's? They'll technically fit in an iPad Air case but the volume buttons have been moved due to the deletion of the mute/rotation lock switch. They won't fit an Air 2 case whatsoever due to the thickness difference of both devices.
I think it's safe to say you're ordering new cases.
@galionschools is right. Cases aren't compatible like they used to be. Air didn't work with Air 2 (and vice versa), and neither work with the 5th gen...
The current targus case we use fits air, air2, ipad pro 9.7, ipad 9.7 2017, im guessing it will fit the newest one also since there were no really big physical changes.
The Dux and the new Logitech with keyboards have been great investments for us with the ability to see inventory stickers or numbering when housed in an Anywhere cart.
