Is it possible to move the file locations of Shared data libraries that have already been added to the system? I just tried moving some of these files to a new location (e.g. /somewhere/files to /somewhere_else/libraries) and updating the galaxy.ini entry to point to the new location. However, files previously added to a library still point to the old location. 
I found this question on biostars:
Is the only way to do this sort of update to manually change such entries in the database?
