August 24, 2025Aug 24 Good afternoon everyone,the USB with Unraid OS recently died recently and I just bought a new one to use.I was planning to use the backup I made some time ago, but I discovered it's on version 6.12.15 of Unraid, while I have upgraded to Unraid 7.1.3 before it died.What are my options? Should it be safe to restore this old backup, then upgrade and just after start the various VM/Dockers?Or should I give up, do a fresh install and then re-configure everything manually?Thanks
August 24, 2025Aug 24 Author It sounds janky to me too, but I could also try to manually upgrade the backup file using the https://docs.unraid.net/unraid-os/manual/upgrade-instructions/#manual-upgrade-or-downgrade guide...?

August 30, 2025Aug 30 Author Thanks Jorge, I followed your advice and re-created a new flash drive and after booting the system with a new unraid installation (to check if the disks were all recognized, i did NOT start the array), I copied the old config folder to the usb and on new boot all the config was there. Furthermore there were also the dockers I created after the backup, I guess those config are saved in appdata.After starting the array it did a parity check but luckily it finished without errors and now everything is working fine.Thanks again!
