Another way to do it should be to install SQLite manager for Firefox :

https://addons.mozilla.org/fr/firefox/addon/sqlite-manager/

The to open the database file (digikam4.db)

Look for "albumsRoot" table and update the identifier field of the
"collection/albumroot"

You'll need to encode the pathname with a tool. For example :
http://meyerweb.com/eric/tools/dencoder/

For example

/mnt/newpath

will then be encoded to

%2Fmnt%2Fnewpath

So the album root identifier should be updated to :

networkshareid:?mountpath=%2Fmnt%2Fnewpath

You should also update the "thumbnails-digikam.db" file so that each
image the new path (more tricky)

Or delete it to automatically rebuild thumbnails.

Of course, as always it is imperative to make a backup before trying to
modify the database !!!
