btrfs send would also have the benefit that I won't lose the source-dev in the process. btrfs-replace would "empty" my hdd, if then things fail I don't have that backup again to start from. I just have to find out how to keep the UUID to keep the copy booting etc I will try that later this day, after some job work.
