Moving from one readynas to another one

This is also a good option however it is not necessary, the advantage of this one is getting the drive ti factory settings so any bad configuration on it will be gone.

I was also considering the benefit of feature 11 of Version 6.1.5
"Improved performance with large volumes (Most likely seen on the ReadyNAS 104). A factory default is required to make the changes. Copy all data off the ReadyNAS, upgrade the firmware, factory default the unit, and copy all data back onto the device"

But is 3TB considered as a big volume? Is there a real improvment in performances?

It is a good idea to install a scratch (spare) disk in the new NAS first, and then install the same firmware running on the original.

So you don't recommand to remove one disk from the raid to move in second NAS to receive datas ?

Then power down, and move the drives to the corresponding slot in the new NAS (with it powered down). The new NAS can have a different number of slots, but it needs to be the same family (v1 sparc, v2 arm, x86 legacy, OS6 arm, or OS6 x86).

Do you think I'll benefit of improvment reported in release note 6.1.5 by doing so. I thought there were some considerations of reformatting disk behind the procedure indicated in 6.1.5#11
