Thanks for your reply.
There is an error when I run migration cmd:
stack@devstack:~/neutron/neutron/db/migration$ neutron-db-manage revision -m

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 -

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
