Newbie Upgrade for Ultra 2 from OS4 to OS6

I have searched the old threads but couldnt find the upgrade for my specific model ( Ultra 2 ).

Recently I switched ISP and I am unable to modify the ports on the provided router. This has then caused me problems accessing my Ultra 2 from outside the home network.

I stumbled upon this forum and would like to seek help if what I will be doing is correct.

I plan on using the 3 step upgrade using a spare blank HDD

"OS6 in 3 Steps: 1. Download pre modified IMG, (R4toR6_6.9.5.bin)
2. Upgrade firmware in Frontview 4.2 (with above file)
3. Reboot & factory default via boot menu"

My Ultra 2 is running RAIDiator 4.2.22 with Bios of 09/08/2010 ReadyNAS-ProUltra2 V1.4

Where do I find the most updated BIOS? is this needed before the upgrade?

Thanks in advance

That's kind of an odd reason to convert the NAS. Can you give more information on how you are accessing the NAS from outside, and what ports you need to forward?

I'd suggest this:

BACKUP, BACKUP, BACKUP

Upload PREPR4TOR6_0.1-x86.bin as an add-on using the ReadyNAS web gui, but do not reboot afterwards (avoids the need to do manual factory resets)

Upload R4toR6_6.9.5.bin using the ReadyNAS web gui firmware update

After you upload the addon/firmware and reboot, it will update the firmware and start a factory default.

Though your method should also work, this just saves the need to do a reset from the boot menu.

Either way, you won't be able to migrate your current array. You'll need to back it up, reconfigure the NAS, and then restore the data from the backup.

You don't need to update the Bios - OS-6 will run fine without doing that. However, if you want to update the bios, it's easier to do that before the conversion.

Iinstalling this as an add-on will update it http://www.readynas.com/download/addons/x86/4.2/BIOS_Update_Package_0.5-x86.bin

I suggest you read ALL of this thread (it is for Pro 6) but equally applies to Ultra too
Upgrade Bios in particular

  As of now, my ISP doesnt allow port forwarding or manipulating the ports of the provided modem. They also dont allow bridged mode of the router. My ISP is also using CGNAT so I think the external IP is shared with other subscribers.
  Right now, I can't access my NAS from outside the home network. Thus unable to use Transmission remote and FTP. If I upgrade to OS6, then I will have access to my files using ReadyCloud from anywhere?
  
  Thanks bedlam1 and StephenB !

    Yes (assuming your ISP is running IPv4).
    
    Another option (with OS6) is to deploy ZeroTier (which shouldn't need port forwarding). But you'd either need to install and configure that from the linux command line or deploy it on a PC, and set up the PC to bridge the ZeroTier SDN to your home network - which is a bit tricky.
