Urbackup Upgrade from source 2.3.8 to 2.4.9

I got a running installation from source. With my first steps. I was doing upgrade from source 2.3.7 to 2.3.8.

I lost every settings. Configure everything new.

But now I want to upgrade from 2.3.8 without this problem. Is there a way to do this without loosing configuration of the urbackup installation?

Any help are welcome.
