I have trouble navigating the Symfony documentation so I create lists of links here so I can just easily find what I need again later.
MigrationsBundle link and info -> shows how to run migrations and all of the doctrine migration related commands
Doctrine Symfony overview -> more information about doctrine and migrations.
I had to dig and dig and dig to find this. Explanation here.
php bin/console doctrine:migrations:diffinstead of making a migration, this command makes the migration file for you. Then you can run this command
php bin/console doctrine:migrations:migrateTo actually change the table.
This post is because I will never remember how I found this link to the list of annotations for doctrine.
