I have had my Apple Watch for long enough to know I like it. I am buying a SS one on eBay and will return my SG Sport. I want to just move all my setup and data to the new one. I looked at the owners manual and it says its backed up to the phone, so not seeing where I can "back up" the phone. Is it really automatic? Has anyone done this before? It won't remove the backup when I unpair the current one? Just looking for some insight from someone that has been through this successfully. I'd rather not have to go back through and try to get everything set again, but can do it if its the only way. Thanks!
