Here are the sql queries which will be used for migration from previous version:

update project_work set work_state = db_id from ir_model_data where module = 'project' and fs_id = 'work_open_state' and state = 'opened';
update project_work set work_state = db_id from ir_model_data where module = 'project' and fs_id = 'work_done_state' and state = 'done';

Should be executed after the update.
