How to read metadata from pic reverse

[cool.chris65 at web.de]

Hi,

I don't know why or how, but when I migrate my Pic-Collections from a local hdd to a NAS 
(and the database from local to a mysql-server on same NAS) I got only a few of metadata 
inside the database.

actually I transfere the data into the database using "read metadata from pic and write to 
database" in the "more"-menue of the caption-sidebar. It works as expectet, but with 
nearly 150.000 Pic and many collection-folders it neets too much time to restore all my 
tags and other metadatas into the database so I ask me if there is an way to do it reversly 
for all collections and fully automaticly?

Greets, Christoph
