Description

If you need to override the ID Generator, e.g. during a migration, you can do that in your migration script as follows:

Overriding the ID generator

$em->getClassMetadata('foo\bar\Entity')->setIdGenerator(new \Doctrine\ORM\Id\AssignedGenerator());
$em->getClassMetadata('foo\bar\Entity')->setIdGeneratorType(constant('Doctrine\ORM\Mapping\ClassMetadata::GENERATOR_TYPE_NONE'));

Make sure that both calls equal to the same generator type. You can now modify the @Id fields in your entities. Additionally, make sure that you set the IdGenerator after you created the database using e.g. SchemaTool->create().
