Assessment of imported servers in Azure Migrate is now generally available.
Azure Migrate supports the assessment of servers imported using a CSV file without the need to deploy an appliance. This is useful if you're looking for a quick assessment using configuration-management database (CMDB) inventory or if you're waiting for approvals to deploy the Azure Migrate appliance. Performance-based assessments can be run as well by specifying utilization values in the CSV.
