IOS10

My iPad Air can be updated with IOS10 but my iPad Mini cannot, probably because it's too old. I wirelessly link these two devices at gigs and am concerned that there might be an issue if I update the iPad Air to IOS10 but the iPod Mini remains on IOS9.

I don't think that will be an issue. Different app versions could create problems, but different iOS versions should be fine.
