Thanks for your reply.
 There is an error when I run migration cmd:


stack at devstack:~/neutron/neutron/db/migration$ neutron-db-manage revision -m 'desc' --contract

You can create new migration using "neutron-db-manage revision -m 'desc' --expand/--contract" depends in what changes do you want to do in migration expand - add something, contract - delete or modify. More information - http://docs.openstack.org/developer/neutron/devref/alembic_migrations.html

Hi, all
    Now, I should make some database model definitions if I want to upgrade db. And a database migration script will generated when I run "neutron-db-manage revision -m "description of revision" --autogenerate". The database will upgraded when run "neutron-db-manage upgrade head". 
    I want to upgrade db and I plan to write db migration scripts manually instead of change database model definitions. Is there some ways to realize it?
    Does anyone have some good ideas?


Thanks
Zhi Chang
