I can not see an easy way to do this. If you have 4 SATA USB and.or eSATA enclosures, use those, as well as the remaining spare internal SATA port. After completion of the data copy, export both pools, shut down the system, connect all the new disks to the internal ports, then import the new pool. If you have a spare computer, build the new pool in the spare computer and copy the data over the network. Then export the pools, connect the new disks to where you want them to be and import the new pool. Some people have tried the "replace the disks one-by-one" strategy, but that is not advisable without a good backup, and in any case requires you to buy two more 1 TB disks. -- Any sufficiently advanced technology is indistinguishable from magic.
