Michael Villeneuve answer is not totally right. In case of a production environnement or kind of , you just can t drop schema and recreate it.

The only way to perform it on your current schema is by the followings :

1. php app/console doctrine:schema:update --dump-sql . Copy the ouptut. Its the direct SQL queries to update your schema
2. connect mysql with mysql command line or through a mysql client
3. Disable foreign keys checking by call this query : "set foreign_key_checks=0;"
4. put the queries from doctrine:schema:update
5. Enable back foreign key checking with : "set foreign_key_checks=1;"

i cannot guarantee you won t lost some keys but you don t drop your datas at all .
