Microsoft App Assure / FastTrack
The FastTrack Center Benefit for Windows Alternative to Citrix AppDNA is Microsoft App Assurance.(New name is FastTrack)
10 provides access to Desktop App Assure – a new service designed to address issues with Windows 10 and Office 365 ProPlus app compatibility. When you request the Desktop App Assure service, a FastTrack Specialist works with you throughout your migration to Windows 10 and Office 365 ProPlus and when you consume feature updates.
A Microsoft engineer works with you to address valid app issues at no additional cost to you with an eligible subscription. We also provide guidance to customers who face compatibility issues transitioning from Office clients to Office 365 ProPlus. This is a service provided by FastTrack and not a software package.
Its also own FastTrack for 365 migration as showed under. For more information see Microsoft own sites.
