I did this on Solaris 10u3. 4 120GB -> 4 500GB drives. Replace, resilver;
repeat until all all drives replaced.

Hi All,
My mate Chris posed me the following; rather than flail about with
engineering friends trying to get a "definitive-de-jour" answer,
I thought instead to introduce him to the relevant opensolaris forum
in the hope of broadening the latter's appeal.
So: RAID-Z hot swap to larger disks and thereby upgrade?
Doable, not, or unwise?
I suspect the proper thing to do would be to build the six new large
disks into a new RAID-Z vdev, add it as a mirror of the older,
smaller-disk RAID-Z vdev, rezilver to zynchronize them, and then break
the mirror.
But I'd like a second opinion?
