The <info>kaliop:migration:generate</info> command generates a skeleton migration definition file:

    <info>./ezpublish/console kaliop:migration:generate bundlename</info>

You can optionally specify the file type to generate with <info>--format</info>:

    <info>./ezpublish/console kaliop:migration:generate --format=yml bundlename migrationname</info>

For SQL type migration you can optionally specify the database server type the migration is for with <info>--dbserver</info>:

    <info>./ezpublish/console kaliop:migration:generate --format=sql bundlename migrationname</info>

For role type migration you will receive a yaml file with the current role definition. You must define ALL the policies you wish for the role. Any not defined will be removed.

    <info>./ezpublish/console kaliop:migration:generate --role=Anonymous bundlename migrationname

For freeform php migrations, you will receive a php class definition

    <info>./ezpublish/console kaliop:migration:generate --format=php bundlename classname</info>
