What Linus and others seem to be thinking is of a
gradual migration of:
ext3 -> ext4 -> btrfs
There are already tools that will let you convert an
existing ext3 (and, I think, ext4) filesystem to a
snapshot within a btrfs filesystem using its COW
features to leave the original data intact.
Details and nice diagram here:
I don't know how that'll work with the inbuilt RAID
functionality of btrfs.
