What is the small risk and how small is it? When does it happen? If it does then is it bricked?

I didn't run into any snags when convering my own Pro 6, and it's been quite a while since I've seen any reports of problems with the conversion.
One scenario is if the the flash has already degraded, in which case the failure would occur when the image was written to it. That would likely be unrecoverable (though with failing flash, the NAS would be on borrowed time anyway).
Another happened here:
I think this was disk-related, and the poster was able to complete the conversion steps.
The main point in the disclaimer is to make it clear that you are doing this conversion at your own risk.

The problem can occur during the conversion or any OS upgrade thereafter. The reason is unclear, most do not have the issue. But several have reported it here. But native OS6 units do not have a vpd file, so Netgear never addressed this issue. They used to have somebody who could re-create it for you, but they no longer provide that. Yes, without a valid VPD, your NAS is essentially bricked. Your only option then is to get one from another unit and load it. Better to back yours up.

Just want to add that this is the case for both 4.2.x and OS-6. So you should back up the VPD even if you decide not to upgrade.
