Limitations * * - Information from the {@link Versioned} extension (e.g. in "SiteTree_versions" table) * will be discarded for translated records. * - Custom translatable fields on your own {@link Page} class or subclasses thereof won't * be migrated into the translation. * - 2.1-style subtags of a language (e.g. "en") will be automatically disambiguated to their full * locale value (e.g. "en_US"), by the lookup defined in {@link i18n::get_locale_from_lang()}. * - Doesn't detect published translations when the script is run twice on the same data set * *

Usage

* * PLEASE BACK UP YOUR DATABASE BEFORE RUNNING THIS SCRIPT. * * Warning: Please run dev/build on your 2.2 database to update the schema before running this task. * The dev/build command will rename tables like "SiteTree_lang" to "_obsolete_SiteTree_lang". * *

Commandline

* Requires "sake" tool (see http://doc.silverstripe.com/?id=sake) * * sake dev/tasks/MigrateTranslatableTask * * *
