Upgrading My Duo

I have the 4TB Duo and I’m looking to upgrade to a 8GB.  What drives do I need to order and where can I get instructions for the upgrade.

Thanks for the help

I don’t even know if its possible. WD doesn’t support or document it, at least… You’d probably have to do a manual reinstall of firmware from scratch.

There is a debricking script knocking about. I’m guessing it would be possible to get two blank drives, prepare them with the debricking script and then using those discs in the MBLD?
