Yes.
1. LibreELEC Configuration -> System -> Backup -> Create System and Kodi Backup
2. Clean Install RPI5 with LE Image + Basic Konfiguration
3. LibreELEC Configuration -> System -> Backup -> Import System and Kodi Backup
Works very well. I do that too.
Hello
I also plan to upgrade from RPi4 to RPi5 and use the skin Aeon Nox Silva. Are my settings there also part of the backup you described?
