June 18, 20233 yr Ok I know I can copy the original flash (failed upgrade) to a directory on the PC, I'm assuming the upgrade would not affect configuration files so that I can just copy them back to the flash drive (USB). But which ones? I also have a Connect backup but trying to not have to redo passwords. Yes I must stick with 6.11.5 as 6.12.0 does not work on my server.

June 18, 20233 yr Author Thanks itimpi If I understand correctly I should be able to use Unraid creation for 6.11.5 and just copy over my old config directory onto the original USB key and be back where I was before the upgrade attempt. Edited June 18, 20233 yr by grumpy
June 18, 20233 yr Solution @grumpy When you upgrade within the GUI (Tools -->> Update OS) a folder named previous is created on the root of the flash drive. This contains the files associated with the previous version of Unraid that was installed on the flash drive. After my failed upgrade to 6.12.0 (would not boot at all), I just copied all of the files in the previous folder back to the root of the flash drive (overwriting everything) and I was back to 6.11.5.

June 18, 20233 yr 12 minutes ago, grumpy said: So you did not need to use Unraid creation to re-do the Usb Boot Key? Nope. Just copied files from "previous" folder to the root of the flash drive. It's like installing a new version of Unraid and leaves the config folder intact.
