ZWave binding updates

Hi All,

Hope I don’t ask something that has been covered already - if so please forgive me.

With the release of 2.4 I was thinking of setting up a new Raspberry from scratch with OpenHABian and restore a V2.3 backup made accordingly to this approach.
Is this something that would work or would I again have to delete all Z-Wave things?
Would it make a difference if I would plug the controller in and install the Z-Wave binding before restoring the backup?
Having to delete all Z-Wave things (and probably Items as done via PaperUI) is something that really scares me…

Thanks a lot!

Chris
