To see detailed information about a migration or migration definition:

    <info>php bin/console kaliop:migration:migration --info migration_name</info>

    <info>php bin/console kaliop:migration:migration --info /path/to/migration_definition.yml</info>

    <info>php bin/console kaliop:migration:migration --delete migration_name</info>

    <info>php bin/console kaliop:migration:migration --fail migration_name</info>

To manually add migration definitions to the migration table, or marking them as skipped:

    <info>php bin/console kaliop:migration:migration --add /path/to/migration_definition</info>

    <info>php bin/console kaliop:migration:migration --skip /path/to/migration_definition</info>
