After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You have an on-premises Hyper-V cluster that hosts 20 virtual machines. Some virtual machines run Windows Server 2016 and some run Linux.
You plan to migrate the virtual machines to an Azure subscription.
You need to recommend a solution to replicate the disks of the virtual machines to Azure. The solution must ensure that the virtual machines remain available during the migration of the disks.
Solution: You recommend implementing an Azure Storage account, and then using Azure Migrate.
Does this meet the goal?

  • A. Yes
  • B. No

Answer is Yes. Azure Migrate is recommended by Microsoft, in favor of Site Recovery. https://docs.microsoft.com/en-us/azure/site-recovery/migrate-tutorial-on-premises-azure

Answer is No. Because the solution must ensure the VMs remain available during the migration activity. In Azure migrate, if you don't shutdown/restart the VMs then there will be loss of data.

Azure Migrate -require shutdown of VMs> Once you’re ready for the production migration, select Migrate from the replicating machines window. That process will prompt you to shut down the virtual machine to avoid any data loss and perform a final replication. It is recommended to do this during off peak business hours, because the virtual machine will be down for a few minutes So Azure site recovery is best to use

Azure Migrate is correct, an Agentless migration does not require shutdown of the VM's as it utilizes the snapshot & delta migration capabilities natively available in Hyper-V (and VMWare, but this question states Hyper-V): https://docs.microsoft.com/en-us/azure/migrate/common-questions-server-migration#how-does-agentless-migration-work

false, it saids on article, clearly... "When you perform the migrate operation on a replicating virtual machine, you have the option to shutdown the on-premise virtual machine and perform one final incremental replication to ensure zero data loss. On performing the migrate option, the replica managed disks corresponding to the virtual machine are used to create the virtual machine in Azure."

fake, we must understand this. Data is still lost. In Migrate > Shut down virtual machines and perform a planned migration with no data loss, select Yes > OK. By default Azure Migrate shuts down the on-premises VM, and runs an on-demand replication to synchronize any VM changes that occurred since the last replication occurred. This ensures no data loss. If you don't want to shut down the VM, select No

Hey firstly read properly "In Migrate > Shut down virtual machines and perform a planned migration with no data loss," but in ques they have asked that VMs remain available during the process So, correct answer --> Azure Site Recovery.

ANY migration that is to avoid data loss requires shutdown of the source VM. Also "Site Recovery attempts to do a shutdown of source VMs before triggering the failover." When they say, VMs must be available 'during the migration of the disks,' for me this does not mean that can't have ANY outage. Both solutions, Azure Migrate and Azure Site Recovery, would replicate the disks while the source VMs are up. And then, both solutions would shut down the source VMs, replicate the last changes, and start the destination VMs.

Totally agree with you. The microsoft documentation says you have the option to shut down the on-premises machine. Not mandatory! It's important if you want to stop the delta between on-premises data and azure. If not you can continue the migration with the on-premises VMs turned on. And you would have the same problem using any migration tool of course. Otherwise how do you think to stop data writes on a on-premises VM during data migration?

This is so Confusing cause according to the Site Recovery steps - VMS continue being accessible ( If an outage occurs, you run a full failover to Azure. You can fail over a single machine, or you can create a recovery plan that fails over multiple machines at the same time. On failover, Azure VMs are created from the VM data in Managed disks or storage accounts. Users can continue accessing apps and workloads from the Azure VM) and I have read most comments here and both solutions seems to offer VMS being up?? https://docs.microsoft.com/en-us/azure/site-recovery/vmware-azure-about-disaster-recovery. As for AZ Migrate The microsoft documentation says you have the option to shut down the on-premises machine. Not mandatory!

The correct answer is B. Azure migrate is the correct option, but you don't have to "implement a storage account" since the target disks are "Managed Disks".

The question doesn't actually say anything about migrating the VM's and cutting them over to Azure. It merely mentions that the disks need to be replicated to Azure and the VM's need to be available during replication. For this reason, I say the answer is yes, Azure migrate can replicate the disk to Azure without requiring downtime.

So, there is a lot of controversy on this question. The VM's needing to be migrated must remain up and no downtime experienced. To me, ASR is the better route to go. With Azure Migrate you have the option to shutdown, then do a final delta to make sure you have everything without any loss of data. Here's my rational; The AM, if you need to shutdown the VM to make sure you have all the data, that's not meeting the requirements of the question by experiencing no downtime. The downtime would come from having the VM's down while making that final sync happen. With ASR the downtime isn't experienced since it's just shuffling the VM's to an alternate location without needing that extra shutdown step. Just my opinion on this.

Answer is Yes for the following reasons: 1. Azure migrate DOES NOT require shutdown. You can simply just select it to not shutdown the VMs 2. Avoiding data loss IS NOT a requirement. Applicable for cases where the VMs might be running stateless apps.

looking at this link (which talks specifically about hyper-v) - https://docs.microsoft.com/en-us/azure/migrate/tutorial-migrate-hyper-v?tabs=UI Azure Migrate requires shut down. so IMO the answer is correct "No".

"..must ensure that the virtual machines remain available during the migration of the disks." Azure migrate ensures the source vms are online while it seeds to azure, then you can shutdown with final sync or even spin up a test migration. Either way it fits the requirement
