I have attached script with two entities.

I have this database version:
$ mysql --version
mysql Ver 14.14 Distrib 5.1.41, for debian-linux-gnu (i486) using readline 6.1

Check line 44. There is CASCADE.
Updating schema by: $ doctrine orm:schema-tool:update

Change CASCADE to NO ACTION
$ doctrine orm:schema-tool:update --dump-sql
ALTER TABLE ArticleItem DROP FOREIGN KEY ArticleItem_ibfk_1;
ALTER TABLE ArticleItem ADD FOREIGN KEY (articleGroupId) REFERENCES ArticleGroup(id) ON DELETE NO ACTION

everything ok, so: $ doctrine orm:schema-tool:update

Change NO ACTION to RESTRICT
$ doctrine orm:schema-tool:update --dump-sql
// no output!!

Change RESTRICT to CASCADE
$ doctrine orm:schema-tool:update --dump-sql
ALTER TABLE ArticleItem DROP FOREIGN KEY ArticleItem_ibfk_1;
ALTER TABLE ArticleItem ADD FOREIGN KEY (articleGroupId) REFERENCES ArticleGroup(id) ON DELETE CASCADE

everything ok, so: $ doctrine orm:schema-tool:update

Change CASCADE to RESTRICT
$ doctrine orm:schema-tool:update --dump-sql
ALTER TABLE ArticleItem DROP FOREIGN KEY ArticleItem_ibfk_1;
ALTER TABLE ArticleItem ADD FOREIGN KEY (articleGroupId) REFERENCES ArticleGroup(id) ON DELETE RESTRICT

everything ok, do: $ doctrine orm:schema-tool:update

Change RESTRICT to NO ACTION
$ doctrine orm:schema-tool:update --dump-sql
// no output!!

So there is no way to update database schema from RESTRICT to NO ACTION and reverse!

Hm you are right, however for MySQL NO ACTION is the same as RESTRICT as stated by http://dev.mysql.com/doc/refman/5.1/en/innodb-foreign-key-constraints.html
