If the game is "dead" it will be because DMM decides to kill it. Its irrelevant who is hosting it - Nutaku or DMM.
If they (DMM) decide to discontinue Chinese or Western edition, they will have zero reason to "transfer" it anywhere. The only "transfer" you can hope of is some "migration" to a new game they are promoting (e.g. you get some bonus in new game for some of old game stuff).
