Flint upgrade from 3.x to 4.x - could not restore from backup

I lost all of my configurations when upgrading my home Flint from 3.x to 4.x.

Prior to the upgrade I backed up my configuration from the luci console.

After the clean upgrade when I restored the router just would not open the wireless page without errors.
I eventually fixed that by reconfiguring everything, but all of the Wireguard server and client configs did not restore and neither did any of the DHCP reservations…

What a royal disappointing pain in the neck restoring all that, it took hours.

Is there a trick to this, how do you guys backup and restore when doing upgrades?


We made 3.216 to be compatible with the 3.X to 4.X upgrade, but there are still some configurations that cannot be saved, which is why we did not push the update notification.

Thanks luochongjun,

I think I had incorrectly assumed that I could use Luci to backup my configuration, and then restore it after the 3. to 4. upgrade.

In future I’m just going to take it that a 3. to 4. upgrade will require everything to be hand reconfigured.

I upgraded my Beryl to the latest 3. code yesterday and I’m still trying to decide if it’s worth going to 4.
