Microsoft just published that from the 5th of August, the exam will be updated and new skills are being added. Also, some of the old skills are being left out. I'm thinking language packs and migrating user data. I'm not seeing it being tested now with the exam.
Still a valuable skill, you think? First thing that comes to mind is that migrating user data is pretty much straight forward with OneDrive. At least, that's how I feel at work helping users.
