It depends on when your EAD expires and if you think you will need it (ie: starting a new job, renewing a driver's license).

Form VIK's experience it appears USCIS looked over his file when he requested his replacement EAD and then decided to he no longer was eligible for DACA. So there's the other question, do you have anything in your background that might cause a termination of DACA if you apply for a replacement (ie: expunged DUI)?
