1) pvcreate on the new array
2) vgextend to add the new array to the volume group
3) pvmove to get the data into the new array
4) vgreduce to disconnect the old array from lvm
5) pvremove to wipe the old array's lvm meta
6) stop the old array
7) mdadm --zero-superblock to clear the old members
8) mdadm --add to put those members into the new array
