Hi folks-
I've got what I feel is a fairly unique situation here and I'm hoping to confirm my thinking to see if I can make this migration work. I have an ESXi 5.5 system that is using napp-it on the storage layer that I'd like to migrate to FreeNAS, along with an existing FreeNAS zfs pool. Let me describe these two systems in detail.

I've got what I feel is a fairly unique situation here and I'm hoping to confirm my thinking to see if I can make this migration work. I have an ESXi 5.5 system that is using napp-it on the storage layer that I'd like to migrate to FreeNAS, along with an existing FreeNAS zfs pool. Let me describe these two systems in detail.
System 1
- Server running ESXi 5.5
- LSI SAS controller with 8 x 4TB WD Red drives (24 hot-swap bays)
- napp-it VM on SSD drive
- Hardware passthrough in VMware on the LSI for direct access to the drives by napp-it
- RAIDZ2 in napp-it, single pool (let's call it "poolA")
- virtual eSAN network in VMware, each VM drive is an NFS share back to a unique napp-it dataset
- Server running ESXi 5.5
- LSI SAS controller with 8 x 10TB WD red drives
- FreeNAS 11.2-U1 on SSD drive
- Hardware passthrough in VMware on the LSI for direct access to the drives by FreeNAS
- RAIDZ2 in FreeNAS, single pool (lets call it "poolB")
- no other VMs
- Power down all the VMs on System 1 with the exception of the napp-it vm
- 'zfs export poolA' on System 1/napp-it
- shut down the napp-it VM
- 'zfs export poolB' on System 2/FreeNAS
- Migrate the physical drives from System 2 to System 1
- Migrate the FreeNAS VM from System 2 to System 1
- Switch the LSI passthrough on System 1 from the napp-it VM to the FreeNAS vm
- Power up the FreeNAS VM and import poolB, confirm that everything works as it used to on System 2
- Import poolA into FreeNAS
- Set up shares for the datasets that held the individual VMs on poolA in FreeNAS and make sure that ESXi sees them as before
- Power up the other legacy VMs on System 1
- Profit
