We are upgrading to new storage hardware. We currently have a 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.
It sounds like you want the equivalent of zfs send/receive, but for
pools instead of filesystems.
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.
I think your best bet is to create the new pool and then use zfs
send/receive for each filesystem.
