Bridge collection batch change of source

[Stefano Sacchelli]

Dear community 

I moved all my photos and video archive from Lacie external HDD to a NAS. I'm now testing several library and functionalities. One of those are the collection I use in bridge. Of course when file is not found Bridge its suggest to "repair" but it requires for example 570 file to be found. There's no option of automatic finding the source file in the new server origin . Am I missing some feature to do so ? 

How can i assign new source to upstream general folder and let bridge finde the files into subfolders? 

Thanks for any advise.
