According to
https://raid.wiki.kernel.org/index.php/RAID_superblock_formats#Converting_between_superblock_versions
if you do it right, you can convert 0.9 to 1.0 (but no1 1.1 or 1.2 since
those use a different disk location to store the superblock).
Of course it does have to be done on a system like the one that created
the raid as far as endianess is concerned.
