ZFS Replication

[B1ng]

Happy Thursday all.

I would like to request advice with regards to moving data between ZFS pools on different machines.

I currently have a 2-bay server with a ZFS Mirror looking after my data. I have acquired a second server with 4 bays, and an additional 2 hard disks of the same size of those in the 2-bay. It is my plan to use all 4 drives in the new server (2 mirrors in the same pool), but my problem is that I don't have an intermediate way of moving the data from one machine to the other.

What would be the most practical means of moving all data from box 1 to box 2, then incorporating the original 2 disks into the new pool in box 2?

Thanks, and peace out.

It was my intention to stripe across both mirrors for maximum benefit, if possible to do so.

I do keep both a local and a remote backup of the critical data, which is only a few hundred Gigabytes. The rest can be re-acquired in the event of a doomsday scenario.

Based on your suggestion, I have created a fresh local and remote copy of all critical data. If I were to remove 1 of the disks from the existing pool, could I then add it as a single disk 'mirror' then replicate the rest of the data? Once completed, I could add in the second disk from the old pool and complete the 2+2 mirror?
