I seem to have created about five different backups of Health data due to resetting my Apple Watch, and getting a new Apple Watch and iPhone 7 Plus. While I've been careful to not lose or delete any of them, and while the USE of the data seems to be seamless, if I try to delete any of the backups, I get the warning that the Health data contained will be lost forever. Since...it's kinda stupid to have to have so many backups to keep around, and I'm sure the number will just grow over the years and newer equipment...is there some way to merge it all together into just one backup? I thought that when I backed up my 6s Plus, then restored to the 7 Plus, that it WOULD merge them, but...nope. Thanks.
