Yes...to an iPad Air and an iPhone 6s.
Not sure if I like it or not, as I've not found anything particularly useful for me, and have noticed some of the settings have moved to strange places in the settings menu. Also there's a warning that turning bluetooth/wifi off via the swipe-up control centre does not actually fully turn it off - and this is a 'feature, not a bug' so that Apple can ensure your bluetooth/wifi connected peripherals can connect to control the device when needed (pencil/keyboard/watch/etc.).
6s went without a glitch, but the ipad had to be restored and all apps/music/ebooks re-downloaded. Apps & music were simple as they either automatically downloaded (for those bought from Apple/iTunes store) or in iTunes on the Mac.
ebooks were another matter altogether, as I only got about 10% of them from iTunes store, and Apple has removed the ebooks option from iTunes 12.7 completely (no workaround anymore).
Decided to give iBooks (on the Mac) a try to see if I could transfer the rest that way - and after 10 minutes of 'transferring books from iTunes' they were all transferred. Couldn't find a way to transfer them to the iPad though, so deleted them from the library and designated iBooks to the 'never use again pile'.
It was only about 30 minuted later when I read that you can manually transfer (but not manage) your ebooks by just drag & dropping them onto your device when connected to iTunes, so decided to do just that.
Unfortunately iBooks had MOVED all my ebooks from my external drive (which iTunes never did) and put them in a iBooks folder with random names, such as '1987kjb12308y123houhno138612ouh398', which was really helpful as I couldn't tell which of the 1500 or so of my ebooks each was without opening each file individually and then putting them back into their respective folders on the external HD (by author of course).
Finally got an app called 'Calibre' to identify & rename them all for me - but still had to transfer them back to my external library, author by author, and with some typo's in the author names it took an hour or so.
Finally transferred a couple of ebooks via the new method, and they showed up as usual on the iPad.
What really annoys me is that it tells you to backup the device before upgrading - which I did, but then only backs up the documents & settings, so the 40gb of music/apps/ebooks had to be re-downloaded/transferred after the upgrade.
