how to modify a pool to increase performance

Hi,

I have a situation in which I have:

POOL1 -  15 193GB devices + 1 1TB device + 4 250GB devices, for a total of ~4.8 TB of storage.

POOL2 -  10 204GB devices + 2 1TB devices + 4 250GB devices, for a total of ~5TB of storage.

So I want to replace this pool with like sized devices, to increase the performance of each pool.

Each pool is a live production database - so I want to be able to perform a live migration.

My first thought was a ifs send/receive action, but that would require downtime.

My second thought would be to modify the pool to be a mirror and let ZFS copy the data,then split the mirror and decommision the original pool.

Howdy, Stranger!
