users have experienced very slow performance. You can
however clone from HDD to HDD or SSD to SSD without these
performance problems. From there my question if anybody
knows of a caveat not to do it in this way if I want to
clone my rpool from HDD to SSD. If none I would rather
walk this path as it is far less trouble.</span></div>

<p>You might want to update sd.conf with this...<br>

<p>I recently added the Evo 850 to it, so it gives me an ashift 13
zpool on it.</p>
<p>That might stop you attaching it to an ashift 9 rpool though. I
created a new rpool (called something else - the name doesn't
matter), replicated the fdisk/slice structure, zfs send/recv the
data across, and installed grub.</p>
