Move everything from one volume to another

[prod]

I've just upgraded my NAS so I can fit 24 HDD now :)

At the moment I have all data on 4 x 3TB in Raidz called NAS
I have just created new volume 6 x 5TB in Raidz2 called Disk5TB

What's the easiest way to move everything across to the new one?

I dont mind if I do 1 shared folder at a time as I only have 6.

Thank you

Create a recursive snapshot at the parent dataset level.
create a replication task for the parent dataset (including child datasets). If the 2 datasets are local, specify 127.0.0.1 as the destination IP address.

Thank you for you response, I am pretty noob just wondering if there user guide on how to do this?

Yes, it's called the FreeNAS User Guide

In fairness, the guide does not really lay this process out. It explains the snapshot options and the replication options though.

Point taken, but given that you described the process, the user guide explains the tools needed to complete it.

I would go as far as claiming that making the leap from "I want to transfer my datasets to a new volume" to "I can use the replication process described in the manual" is something anyone planning to run a FreeNAS system needs to be capable of. This is not to say that describing it explicitly in the manual would be a bad thing.

@prod, if you can parse man pages and aren't scared of the CLI, you might find the process of using zfs send and zfs recv easier for a one-time transfer.
