Azure Migrate : Consumption and AZ

Question

Hello,

We Would like to Migrate a huge workload from AWS to Azure using Azure Migrate : Server Migrate. We would like to know below 2 things, as it is not available in Microsoft Learn.

1. What will be the compute capacity of CPU, Memory and Network usage of the Source AWS VM.
2. What will be the compute capacity of CPU, Memory and Network usage of the Replication Appliance Vm.
3. As per Server Migrate, it will not support Multiple AZ movement. Is there a way to move the VM's to other zones from a Region if we migrate all the VM's to a single region and later to multiple AZ.

Thanks.

@Arjun Cloud Associate Sorry for delay in response to your query.

It’s not clear what you’re asking with this question: “What will be the compute capacity”.

Azure Migrate has the assessment engine that will give you estimated targets for CPU, Memory, and Storage equivalent in Azure.

As for the third question about availability zones, per this FAQ page it is not supported yet.

As a workaround, you can use Azure Site Recovery (ASR) to migrate from non-Zone into Zone-specific configurations (within the same region), after you have migrated the VMs into Azure.

@Arjun Cloud Associate For the Replication Appliance, the CPU and memory requirements are documented here (in addition to other hardware requirements). The network usage will use the available bandwidth or it can be throttled on the appliance. On the source AWS VMs, the mobility service agent uses approximately 6% - 10% of memory.

In case you haven’t seen it, there’s a tutorial page in the docs to assess and migrate AWS VMs to Azure.
