The <info>%command.name%</info> command executes a migration to a specified version or the latest available version:

    <info>%command.full_name%</info>

You can optionally manually specify the version you wish to migrate to:

    <info>%command.full_name% FQCN</info>

You can specify the version you wish to migrate to using an alias:

    <info>%command.full_name% prev</info>
    <info>These alias are defined : first, latest, prev, current and next</info>

You can specify the version you wish to migrate to using an number against the current version:

    <info>%command.full_name% current+3</info>

You can also execute the migration as a <comment>--dry-run</comment>:

    <info>%command.full_name% FQCN --dry-run</info>

You can output the would be executed SQL statements to a file with <comment>--write-sql</comment>:

    <info>%command.full_name% FQCN --write-sql</info>

Or you can also execute the migration without a warning message which you need to interact with:

    <info>%command.full_name% --no-interaction</info>

You can also time all the different queries if you wanna know which one is taking so long:

    <info>%command.full_name% --query-time</info>

Use the --all-or-nothing option to wrap the entire migration in a transaction.
