Before there's the batch tool to do that, somebody suggested a trick to 
do that :

It doesn't appear as if a batch processing mode exists to automatically 
update the existing tags, however, I discovered a simple workaround that 
will do it for you.

Step 1: Create a new tag called "temp". You can do this be selecting 
Comments/Tags from the right sidebar, then right-clicking in the My Tags 
section. An image must be selected for the menu to appear.

Step 2: Select Tag Filters from the right sidebar and check all of the 
tags except "temp". This will only select pictures that already have a tag.

Step 3: Select all images. Right-click on one of them and pick "temp" 
from the Assign Tag menu. This step will add all assigned tags each 
file's IPTC data. With a large number of photos it could take a while 
for everything to complete.

Step 4: Cleanup. Repeat the previous step by selecting all images, but 
this time pick "temp" from the Remove Tag menu. Now you can delete the 
"temp" tag and you are done.

Note: I never tested this trick myself :)
Use at your own risk...
