As of February 1, 2020, all cloud services will be retired from Deployment Planning Services in favor of FastTrack deployments. Microsoft consolidats their programmatic deployment planning assistance to a single approach, and Microsoft FastTrack is our primary implementation support offer. You can use FastTrack for Azure, Microsoft 365, and Dynamics 365 engagements.
All on-premises Deployment Planning Services offerings and the respective engagements will be available until January 2022 and you can continue to redeem your deployment planning days through the current process from qualified partners or Microsoft Consulting Services to help you plan your deployment, whether on-premises or in hybrid environments. These structured engagements help you plan your deployment of the latest Microsoft technology.
