zfs discuss - May 2010 - Migrating ZFS/data pool to new pool on the same system

Can anyone confirm my action plan is the proper way to do this?  The reason
I''m doing this is I want to create 2xraidz2 pools instead of expanding
my current 2xraidz1 pool.  So I''ll create a 1xraidz2 vdev, migrate my
current 2xraidz1 pool over, destroy that pool and then add it as a 1xraidz2 vdev
to the new pool.

I''m running b130, sharing both with CIFS and ISCSI (not comstar),
multiple decedent file systems.  Other than a couple VirtualBox machines that
use the pool for storage (I''ll shut them down), nothing on the server
should be messing with the pool.  As I understand it the old way of doing iSCSI
is going away so I should plan on Comstar.  I''m also thinking I should
just unshare the CIFS to prevent any of my computers from writing to it.

So migrating from pool1 to pool2 
0. Turn off AutoSnapshots
1. Create snapshot -> zfs snapshot -r pool1 at snap1 
2. Send/Receive -> zfs send -R pool1 at snap1 | zfs receive -F -d test2
3. Unshare CIFS and remove iSCSI targets.  For the iSCSI targets, seems like I
can''t re-use them for Comstar and the reservations aren''t
carried over for block devices? I may just destroy them before hand.  Nothing
important on them.
4. Create new snapshots -> zfs snapshot -r pool1 at snap2
5. Send incremental stream -> zfs send -Ri snap1 pool1 at snap2 | zfs receive
-F -d test2
Repeat steps 4 and 5 as necessary.
6. Offline pool1... if I don''t plan on destroying it right away.

Other than zfs list, is there anything I should check to make sure I received
all the data to the new pool?
