Moving my music to a NAS

What is the best way to move my music to a Synology NAS from my PC? I would like to maintain my playlists, favorites & ratings if possible. I assume just copying the music over won't keep the ratings & I guess the playlists won't work unless I change all the tags from D: to what I assume will now be C: on the NAS, am I right? I am also using JRiver to play music on the PC so those playlists will probably be useless also.

Thanks for any advice.
