ZFS to ZFS Data Migration

[wombat-fertilizer]

I searched the forums and didn't find anything on this precise scenario...

I setup a new TrueNAS (current) system with 1 pool and want to migrate my data off the old FreeNAS (11.3-U2.1) with 2 pools, 13.5 TB total.

I have them directly connected with dual 10gb SFP's in LACP configuration.

What's the 'best' way to accomplish this? RSYNC? ZFS Replication? My priority is data integrity fist and speed second.

You can probably get both things with ZFS replication.

Either set it up in the GUI to replicate or use zettarepl at the CLI (or use zfs send | zfs recv on a recursive snapshot of your choice manually)
