Mario,
I have migrated from Fred 2.1 to 2.11 successfuly , I had to tune the migration scripts as I realised some errors if you do not tune them.I have attached a text file with the notes I took when i was upgrading i am not sure if it will help much.If I was facing that problem i would go back to the upgrade script and look for the sql statement that update that particular table and see why it is not working and tune it to make it work the way it is required as I am sure once you tune the script to add the column service the error will disappear.
One problem i face is when i was upgrading the invoice table and other related credit tables to the new one it did not work because what happens is that the scripts generate the text file from the table,delete the tables and then create new table upload from the text file,now if the user does not have enough permission to do that you will fail.I know this is not your problem but just incase you suffer such a problem.
Finally I can just say the upgrade works after some tuning!
