As CAM suggested, it would basically be a CoW, with a checksum
comparison at the end to make sure no data has been corrupted.

In-place: Without taking the drives or filesystem offline or unmounting
them. Doing the conversion while the rest of the RAID is in use.
Risky, slow, but possible, given enough time for large data sets.
