zfs pool migration

I need to migrate an existing raidz pool to a new raidz pool with larger disks. I need the mount points and attributes to migrate as well. What is the best procedure to accomplish this. The current pool is 6x36GB disks 202GB capacity and I am migrating to 5x 72GB disks 340GB capacity.

I've never done a raidz before, but is mirroring an option ?

Failing that, you could do a zfs send/receive ....

Ok have the send/recv working, and going to use zpool destroy oldpool, zpool export newpool, zpool import newpool oldpool. My issue now is to make sure all the settings and attributes migrate. So how do I first gather them on oldpool and then set them on newpool.
