I want to migrate my Truenas Mini to new Hardware , but leave the drives with the old system.

[Rob Granger]

I have a truenas mini, 4 drives w/ raidz. I will be moving to 6 drives with raidz+2. When I create the new system. Do I reload my saved config first or create the Pool first and then restore the config. I was thinking that I could build the new sever, setup the /mnt/tank pool and then sync the contents over. I won't have enough sata connections to have the boot drive, and 6 data drives and the 4 old drives connected to the new box.

I think I setup a signature with system info, but... first time posting in years and years.

I solved part of my drive issue: bought an Icy Dock 6 drive cage that I have connected to the old system.
I have started copying the old pool "tank" to the new pool "new-tank"
Once this completes how do I keep the new pool current until I am ready to move the cage to the new server?
I have tried several replication jobs, but I seem to keep screwing the pooch (failures below)
I don't need to keep it in an ongoing state of being current, just wanted to seed the process so that I can freshen up the pool before moving it over.
Thanks in advance,
