Doctrine migration process tips

octobre 2010

Has I’d to migrate few times and had always the same problem I would note how I resolved problem within migration process (you know, when an exception occures during migration… un finished database migration)

First : DB Dump

./mysqldump --add-drop-database -u DBUSER -p --databases DB > ~/DB-dropdb.sql

Second : Doctrine Migrate

php symfony doctrine:migrate

Then if everything’s fine you can continue, it something goes wrong, restore previous state :

./mysql -u DBUSER -p DB < ~/DB-dropdb.sql
