I am a MediaWiki translator (into russian). I want to mark pages for translation and if it already have done translation into russian without the Translate extension migrate it. I have read Help:Extension:Translate/Page_translation_administration and Project:Language_policy, but I have one question (if tou give me requested permission): if page have translation without without the Translate extension, I should migrate all translations or I can migrate only russian translation?
