Is there a way to do this without rescanning the whole library? For ex by changing ip to the new nas? The library contains about 3000 movies.
I haven't tried this, but there is a synchronisation function to do it. First make a backup so if you bugger it up you can go back to the original settings!! Add the new NAS with the same content as the old one as a source but DON'T scan it (press <return> when it asks to scan). Then press <menu> and select "Synchronise data from other source" and point to the first NAS. As I say, I've never tried this so there might be a bit of trial and error...
