If a raid5 is changed to raid6, and then the raid6 is grown w/

I'd greatly appreciate if someone in the know could answer this?
Also, this raid6 with all Q blocks on a single drive, will older kernels
read this as well or is 2.6.30 needed to handle this "new" layout?
I'd like to convert a raid5 to raid6 with 2.6.30, then go back to 2.6.28
and run it, then when I grow it next time, I'd like to get the "correct"
layout with the Q blocks striped just as if I had created the raid6 from
scratch. Is this possible?
