SOLVED Downgrade failure from TrueNAS core 13

[Liamrahum]

Hey, I'm using the latest version available for TrueNAS core right now (13.0-U1) and I've been trying to downgrade it manually through the upgrade panel (to version 12.0-U8.1), it didn't work. I got this error and I hoped you could help me

Thanks in advance :)

Save your config, with secrets. Then clean install 12.0-U8.1. After the system is up, restore your config. This will accomplish the same thing.

Yes, that doesn't work at all.

If you don't like the new version, just change your boot environment to the old one and go straight back.

System | Boot | Select the old environment, ... Activate (reboot)

So I've tried that, but I can't use a newer version's config on an older version
All I want is to restore my pools so I won't have to reset them again

Nevermind, I imported them!
Thank you for your help :)
