FreeBSD 9.3-RELEASE-p31
So currently I've a 2x4tb mirrored volume setup in freenas (zfs). While first I wanted to be more on the safe side, I've realized that I don't have that important data and storage space is not free and I'm running short.
I've ordered another two 4tb drives and they should arrive shortly. I thought about switching my current 100% mirrored setup to something like a RAID 5.
Usable space would be 12tb then, instead of just 8.
Now my questions:

Now my questions:
- First, is it even possible to migrate my current setup to the wanted new 4-drive setup, without loosing any data? (I only have those 4 drives (while 2 have my data), nothing else where I can do a temporary backup)
- On a real RAID, I could copy my data to a single new disk > format the other 3 to a RAID 5 > copy data back to 3-drive setup > format 4th drive and extend RAID 5, right?. How would I do something similiar in freenas zfs?
