Hi Tania - Here is a clue, just read the first section:
    
http://typo3.org/documentation/document-library/extension-manuals/dam/1.0.11/view/1/5/ 


I stumbled upon this with the upgrade on a DAM installation.  You may 
need to examine that extension to see what they did. Okay, I looked at 
my copy. Look in the file tx_dam/class.ext_update.php. They had to 
rename an mm field "sorting" to "sorting_foreign".

You may need to do the legwork to understand the MM file handling 
changes; or maybe someone who knows can point you to further 
documentation of the changes.

Make it a good day,
Curt
