Azure migrate disk assessment

Jamie Childs 21

Does anyone know how azure migrate handles on premise disk constraints when performing an assessment? E.g will it read disk queues when advising on the disk type to use within azure?

From the XML that you shared, it looks like all the performance counters are missing for these VMs. Can you please ensure that:
• If the VMs are powered on for the duration for which you are creating the assessment
• If all of the performance counters are missing, ensure that outbound connections on ports 443 (HTTPS) are allowed.
• Connection status of the assessment agent is connected and you can see a latest datetime on the last heartbeat (To check this, click on the number of assessment from the Server Assessment tile > Under Manage, click on Appliances > and you can see agents under Agent health)

@Jamie Childs Thanks for your patience in this matter!

For storage sizing in an Azure VM assessment, Azure Migrate tries to map each disk that is attached to the machine to an Azure disk. The sizing logic changes with the Sizing criteria chosen in the assessment properties as below:
• As on-premises: The assessment logic does not consider the performance history of disks and only looks at the on-premises disk size and storage type specified in assessment properties to recommend appropriate disk type. Possible storage types are Standard HDD, Standard SSD, and Premium.
• Performance-based: Along with the disk size and storage type, the logic also considers IOPS and throughput of individual disks to find the appropriate disk in Azure. More details here
