Running Migrations
The reference documentation for running migrations can be viewed in the usual way:
php index.php migrations:run --help
Find out where you are
At any time, the current status of completed and pending migrations can be found with:
php index.php migrations:status
There are no options for status (other than --help).
Go up
To migrate your schema to the latest possible version run the command:
php index.php migrations:run --up
This will run all migrations that haven't yet been applied.
Go down
To reverse all migrations (i.e. to delete all the tables in your schema) run this command:
php index.php migrations:run --down
Note that this will actually only go down as far as the lowest migration
configuration value (defined by minion/migration.lowest_migration).
Go over there
If you want to a specific version of your schema then you can use the --to switch,
which accepts either a migration's timestamp or a relative pointer to a migration.
This must be used with the --group switch.
# Migrate the schema 5 versions down
--to=-5
# Migrate the schema 10 versions up:
--to=+10
# Migrate to a specific version
--to=201102190811
Look before you leap
If you want to see what a Migration is going to do then you can use the --dry-run switch
and the SQL will be printed to the console instead of being executed.
