Replication of existing pool for hard drive replacement

[theaddies]

I have a pool of 10 x 2TB drives (RaidZ2) that I want to move to few larger drives and increase the overall size. 7x10TB (RaidZ2) The problem is that I am out of SATA connectors on the motherboard. Can I perform a replication to a USB 3.0 drive? I just want to make a copy and immediately remove all the old drives, replace with the new drives and reload the replication. TIA

USB drives are not recommended "for production", but as a temporary backup it should work. (I'd be tempted to put the temporary drive on a SATA port, tough, and move one of the old drives to USB so that the most important connection is "safe".)
Since you'll keep the old set of drives through the procedure, there will always be a backup to revert to if anything goes wrong.

Great suggestion!!
