Hi,
you can try to manually add column tt_row_number to table dct_threshold_instances (integer not null, set it to 0 if you have any records in dct_threshold_instances table), then you can try to run upgrade with -X option (it will ignore upgrade errors and continue). One of next upgrade procedures will try to rename row_number to tt_row_number, so you should end up with correct schema.
Make sure you have database snapshot or backup before trying this, and watch for possible other errors, because with -X DB manager would not stop at them anymore.
Best regards,
Victor
