OH4 install issues

Hi, what I’ve done in the meantime.
I installed Openhabian v1.8 on new Hardware.
Afterwards I restored a backup of my “old” openhab 3.4.4 installation, which worked flawless.
I “only” got this error message:

2023-06-27 16:28:15.595 [WARN ] [core.karaf.internal.FeatureInstaller] - The transformation add-on 'javascript' does not exist - ignoring it.

Anyone an idea, what caused this?

Now im installing 3rd party software, and will do testing.
I keep you informed

Fixed it:

fixed with running

java -jar $OPENHAB_RUNTIME/bin/upgradetool.jar

and changing in /var/lib/openhab/config/org/openhab/addons.config

old: transformation="map,regex,xslt,exec,javascript,scale,xpath,jsonpath"
new: transformation="map,regex,xslt,exec,scale,xpath,jsonpath"
