I just received a new-in-box Nike Series 4 that likely has some variant of watchOS 5 on it. I am currently using a Series 1 on the latest watchOS 6 release and plan to transfer all of my data and achievements to the new Series 4 watch. Given that I wont be able to update to watchOS6 until after I pair my new Series 4 to my phone, are there any precautions or procedure I need to take to ensure my data is properly transferred from my old watch and not lost? Maybe it's more straight forward than I think, but figured I'd reach out for insight if necessary. The older watchOS is the only part that potentially worries me.
