70-533 will be replaced by 31.12.2018 with these 2 Beta exams: AZ-100 and AZ-101. The beta exams are free, as usual, but you have to pay 20% in advance for them and you get a 25% voucher for your next Microsoft exam.
The official training for 533 is 5 days long, for AZ-100 plus AZ-101 are 9 days (!), due more complex learnings. The 533 exam result / certificates will be still valid. There will be also an upgrade exam for 533.
