With the new version of FreeNAS coming out recently, I decided to upgrade to the newest version of FreeNAS. To begin I backed up the configuration of the existing FreeNAS server by logging into the FreeNAS panel and going and selecting Save config.
From there I downloaded the newest FreeNAS version for flash and burned it onto new USB drive:
xzcat FreeNAS-9.2.0-RELEASE-x64.img.xz | pv | dd bs=1M of=/dev/sdb sync
Note: Make sure to flash through
I then replaced the original USB drive with the old version of FreeNAS with the newer USB drive and booted it up. After identifying the IP address, I opened a web browser and pointed it at the IP address of the FreeNAS box. I was immediately prompted to change the admin password, after doing so I went to the of the new FreeNAS install and selected Upload Config and uploaded the configuration from the previous FreeNAS installation. I was again prompted to change the admin password, and again changed it.
The server upgrade finished with a few minor hiccups. One being the BIOS was not set to boot from the new USB drive, this was fixed by rebooting the machine and pressing [F2] at boot time and going to the section and change the priority of the boot order.
