Just another data point: when I switched to btrfs in the middle of last year I
used btrfs-convert on two file systems (an SSD and my backup partition on a
USB 3.0 HDD), and it worked in both cases (i.e., no data loss). I did see some
strange balance issues (see the ML archives), but IIRC nothing really serious.
