Migration Order With Foreign Keys

Hello,

I created two migrations with joined tables (the post table having a foreign key towards the author table): create_post_table and create_author_table.

Is the order of these two migrations important ?

If 'create_post_table' is executed before 'create_author_table', might this lead to an error when Yii tries to create a foreign key towards a table that does not exist ?

Thank you for your clarification,

Fab
