Either run 3.4 with Java 11 or 4.0 with Java 17.

Did you run the upgrade tool after import ?

Actually, because I have many and many bindings and item, rules and transformation script I did as follow: openhab-cli --full backup Installed in a fresh sd card to last openhabian 4.0.1 (keeping the 3.4.4) openhab-cli restore Did I miss something?
