[osol-discuss] How to "mirror" an entire zfs pool to another pool

We are upgrading to new storage hardware.  We currently have a zfs pool with 
the old storage volumes.  I would like to create a new zfs pool, completely 
separate, with the new storage volumes.  I do not want to just replace the old 
volumes with new volumes in the pool we are currently using.  I don't see a way 
to create a mirror of a pool.  Note, I'm not talking about a mirrored-pool, 
meaning mirrored drives inside the pool.  I want to mirror pool1 to pool2.  
Snapshots and clones do not seem to be what I want as they only work inside a 
given pool.  I have looked at Sun Network Data Replicator (SNDR) but that 
doesn't seem to be what I want either as the physical volumes in the new pool 
may be a different size than in the old pool.

  Does anyone know how to do this?  My only idea at the moment is to create the 
new pool, create new filesystems and then use rsync from the old filesystems to 
the new filesystems, but it seems like there should be a way to mirror or 
replicate the pool itself rather than doing it at the filesystem level.
