Promoting a Launch
When content is translated for an existing language copy, review the translations, make changes if necessary, and then promote the translations to move it to the language copy. You need to promote launch pages to move the content back into the source (Production) before publishing.
You can review translated files when their translation job has Ready For Review status.
When a launch page is promoted, the corresponding page in the source pages is replaced with the promoted page content. For more details, see Promoting a Launch (Adobe Inc. online help).
