Why wouldn't they fit? You are taking about 0.05in in height. Everything else is the same.
There is always some wiggle room in these cases. You should be fine.
Nope. They don't. Just bought two new 9.7 smart covers. Fits my wife iPad Air 2 no probs. But will not stay on my 9.7 IPP. The prob is the side attachment.
The OP said "cases" not "covers" so I was assuming they were asking about a case. I've helped several friend buy a "case" for their iPad 9.7 that said on the box its for a 9.7 Pro. We picked up a Poetic rugged case for the Pro that fits for the 9.7in.
Case = backside
cover = front side
