You are in for a treat. The newer cameras have MUCH better image quality. Note that if you just replace the camera, you'll get the same image quality as now. You'll need to go into the settings in the Meraki Dashboard and turn the image quality up.
This is for a different model camera, but this is where you configure it.

If you go to this URL there is a wizard where you can select what you want in a camera, and it recommends models:

If I select "Fixed-lens fisheye" and "Indoor" it recommends these models:
MV33M
MV33
MV32
I agree with @rwiesmann . The MV33 is the most direct replacement. The MV33M is like the MV33 but has much more storage, so much better retention. I would lean towards the MV33M personally.
If you want ultra-high quality, removing the "Indoor" requirement, there is also the MV84X (it uses four cameras to create the 360-degree view):

This is a datasheet that allows you to easily compare the cameras.

And lastly, all the cameras use the same licence. So you only need to buy the replacement camera - you don't need to pay for another licence (just remove the dead MV32 from the network).
