So Im a little confused now. Are you saying just leave from plugged in with WiFi overnight so it backups up with icloud and I should be good in the morning?
You're talking a comment I made to another poster out of context. I was referring to general back up habits, not to your specific situation.
In order to transfer your Health data from one device to another, you will have to back up the original device, either using iCloud or an encrypted back up in iTunes. Then, you'll need to restore the new device from that back up. See this article for instructions:
