Are the rrd4j persistence files of openhab 1 compatible with openhab 2

Setup, Configuration and Use 1.x Compatibility
1

I have copied the files that have been created by openhab and the rrd4j persistence service to the user folder of openhab 2
It seems that items cannot restore their value from these files.

Is this a known imcompatibility?

No, as the rrd4j jar is exactly the one from openHAB 1, this should be compatible.
The only difference is that the location of the files has changed. Instead of /etc, they are now located in /userdata.

Thanks for the feedback.
I have to check my setup again. Must have done something wrong
