Importing RATINGS from other music system (Synology Audio Station)

[erik6]

I was looking to import the ratings that I have made in mi DS Audio system in to Musicbee. The same as for the playlists.  But this is not so simple as that!

This is the tread I found in the Synology Forum.
How or where are song ratings saved?

All suggestions, workaround, etc,  are welcome
