Support to assess physical servers is now generally available in Azure Migrate. This feature can also be used to assess virtual machines on Amazon Web Services (AWS), Google Cloud Platform (GCP) or any cloud, on-premise machines of any virtualization or VMware / Hyper-V machines where there is no access to the hypervisor. The assessments offer Azure suitability analysis, migration cost planning and performance-based rightsizing. Support for application dependency analysis (agent-based) is also available. Upto 1000 servers can be discovered per appliance, and any number of servers per Azure Migrate project.
