Migrate VMware VMs to Azure (agentless) - PowerShell

  • Article

In this article, you learn how to migrate discovered VMware virtual machines (VMs) with the agentless method by using Azure PowerShell for Migration and modernization.

You learn how to:

  • Retrieve discovered VMware VMs in an Azure Migrate project.
  • Start replicating VMs.
  • Update properties for replicating VMs.
  • Monitor replication.
  • Run a test migration to make sure everything's working as expected.
  • Run a full VM migration.

Note

Tutorials show you the simplest deployment path for a scenario so that you can quickly set up a proof of concept. Tutorials use default options where possible and don't show all possible settings and paths.

If you don't have an Azure subscription, create a free account before you begin.

Prerequisites

Before you begin this tutorial, you should:

Install the Azure Migrate PowerShell module

The Azure Migrate PowerShell module is available as part of Azure PowerShell (Az). Run the Get-InstalledModule -Name Az.Migrate command to check if the Azure Migrate PowerShell module is installed on your machine.

Sign in to your Azure subscription

Sign in to your Azure subscription with the Connect-AzAccount cmdlet.

Connect-AzAccount

Select your Azure subscription

Use the Get-AzSubscription cmdlet to get the list of Azure subscriptions you have access to. Select the Azure subscription that has your Azure Migrate project to work with by using the Set-AzContext cmdlet.

Set-AzContext -SubscriptionId 00000000-0000-0000-0000-000000000000

Retrieve the Azure Migrate project

An Azure Migrate project is used to store discovery, assessment, and migration metadata collected from the environment you're assessing or migrating. In a project, you can track discovered assets, orchestrate assessments, and perform migrations.

As part of the prerequisites, you already created an Azure Migrate project. Use the Get-AzMigrateProject cmdlet to retrieve details of an Azure Migrate project. You need to specify the name of the Azure Migrate project (Name) and the name of the resource group of the Azure Migrate project (ResourceGroupName).

# Get resource group of the Azure Migrate project
$ResourceGroup = Get-AzResourceGroup -Name MyResourceGroup

# Get details of the Azure Migrate project
$MigrateProject = Get-AzMigrateProject -Name MyMigrateProject -ResourceGroupName $ResourceGroup.ResourceGroupName

# View Azure Migrate project details
Write-Output $MigrateProject

Retrieve discovered VMs in an Azure Migrate project

Azure Migrate and Modernize uses a lightweight Azure Migrate appliance. As part of the prerequisites, you deployed the Azure Migrate appliance as a VMware VM.

To retrieve a specific VMware VM in an Azure Migrate project, specify the name of the Azure Migrate project (ProjectName), the resource group of the Azure Migrate project (ResourceGroupName), and the VM name (DisplayName).

# Get a specific VMware VM in an Azure Migrate project
$DiscoveredServer = Get-AzMigrateDiscoveredServer -ProjectName $MigrateProject.Name -ResourceGroupName $ResourceGroup.ResourceGroupName -DisplayName MyTestVM | Format-Table DisplayName, Name, Type

# View discovered server details
Write-Output $DiscoveredServer

We migrate this VM as part of this tutorial.

You can also retrieve all VMware VMs in an Azure Migrate project by using the ProjectName and ResourceGroupName parameters.

# Get all VMware VMs in an Azure Migrate project
$DiscoveredServers = Get-AzMigrateDiscoveredServer -ProjectName $MigrateProject.Name -ResourceGroupName $ResourceGroup.ResourceGroupName

If you have multiple appliances in an Azure Migrate project, you can use the ProjectName, ResourceGroupName, and ApplianceName parameters to retrieve all VMs discovered by using a specific Azure Migrate appliance.

# Get all VMware VMs discovered by an Azure Migrate Appliance in an Azure Migrate project
$DiscoveredServers = Get-AzMigrateDiscoveredServer -ProjectName $MigrateProject.Name -ResourceGroupName $ResourceGroup.ResourceGroupName -ApplianceName MyMigrateAppliance

Initialize replication infrastructure

Migration and modernization uses multiple Azure resources for migrating VMs. Migration and modernization provisions the following resources, in the same resource group as the project.

  • Service bus: Migration and modernization uses the service bus to send replication orchestration messages to the appliance.
  • Gateway storage account: Migration and modernization uses the gateway storage account to store state information about the VMs being replicated.
  • Log storage account: The Azure Migrate appliance uploads replication logs for VMs to a log storage account. Azure Migrate applies the replication information to the replica-managed disks.
  • Key vault: The Azure Migrate appliance uses the key vault to manage connection strings for the service bus and access keys for the storage accounts used in replication.

Before you replicate the first VM in the Azure Migrate project, run the following command to provision the replication infrastructure. This command provisions and configures the preceding resources so that you can start migrating your VMware VMs.

Note

One Azure Migrate project supports migrations to one Azure region only. After you run this script, you can't change the target region to which you want to migrate your VMware VMs. You need to run the Initialize-AzMigrateReplicationInfrastructure command if you configure a new appliance in your Azure Migrate project.

In this article, we initialize the replication infrastructure so that we can migrate our VMs to the Central US region.

# Initialize replication infrastructure for the current Migrate project
Initialize-AzMigrateReplicationInfrastructure -ResourceGroupName $ResourceGroup.ResourceGroupName -ProjectName $MigrateProject. Name -Scenario agentlessVMware -TargetRegion "CentralUS"

Replicate VMs

After you finish discovery and initialize the replication infrastructure, you can begin replication of VMware VMs to Azure. You can run up to 500 replications simultaneously.

To specify the replication properties, use the following table.

Parameter Type Description
Target subscription and resource group Mandatory Specify the subscription and resource group that the VM should be migrated to by providing the resource group ID by using the TargetResourceGroupId parameter.
Target virtual network and subnet Mandatory Specify the ID of the Azure Virtual Network instance and the name of the subnet to which the VM should be migrated by using the TargetNetworkId and TargetSubnetName parameters, respectively.
Machine ID Mandatory Specify the ID of the discovered machine that needs to be replicated and migrated. Use InputObject to specify the discovered VM object for replication.
Target VM name Mandatory Specify the name of the Azure VM to be created by using the TargetVMName parameter.
Target VM size Mandatory Specify the Azure VM size to be used for the replicating VM by using the TargetVMSize parameter. For instance, to migrate a VM to D2_v2 VM in Azure, specify the value for TargetVMSize as Standard_D2_v2.
License Mandatory To use Azure Hybrid Benefit for your Windows Server machines that are covered with active Software Assurance or Windows Server subscriptions, specify the value for the LicenseType parameter as WindowsServer. Otherwise, specify the value as NoLicenseType.
OS disk Mandatory Specify the unique identifier of the disk that has the operating system bootloader and installer. The disk ID to be used is the unique identifier (UUID) property for the disk retrieved by using the Get-AzMigrateDiscoveredServer cmdlet.
Disk type Mandatory Specify the type of disk to be used.
Infrastructure redundancy Optional Specify the infrastructure redundancy option as follows:

- Availability zone: Pins the migrated machine to a specific availability zone in the region. Use this option to distribute servers that form a multinode application tier across availability zones. This option is only available if the target region selected for the migration supports availability zones. To use availability zones, specify the availability zone value for the TargetAvailabilityZone parameter.
- Availability set: Places the migrated machine in an availability set. The target resource group that was selected must have one or more availability sets to use this option. To use an availability set, specify the availability set ID for the TargetAvailabilitySet parameter.
Boot Diagnostic Storage Account Optional To use a boot diagnostic storage account, specify the ID for the TargetBootDiagnosticStorageAccount parameter.
- The storage account used for boot diagnostics should be in the same subscription to which you're migrating your VMs.
- By default, no value is set for this parameter.
Tags Optional Add tags to your migrated VMs, disks, and NICs.
Use Tag to add tags to VMs, disks, and NICs or:
- Use VMTag to add tags to your migrated VMs.
- Use DiskTag to add tags to disks.
- Use NicTag to add tags to network interfaces.
For example, add the required tags to the variable $tags and pass the variable in the required parameter: $tags = @{Organization=”Contoso”}.

Replicate VMs with all disks

In this tutorial, we replicate all the disks of the discovered VM and specify a new name for the VM in Azure. We specify the first disk of the discovered server as OS Disk and migrate all disks as Standard HDD. The OS disk is the disk that has the operating system bootloader and installer. The cmdlet returns a job that can be tracked for monitoring the status of the operation.

# Retrieve the resource group that you want to migrate to
$TargetResourceGroup = Get-AzResourceGroup -Name MyTargetResourceGroup

# Retrieve the Azure virtual network and subnet that you want to migrate to
$TargetVirtualNetwork = Get-AzVirtualNetwork -Name MyVirtualNetwork

# Start replication for a discovered VM in an Azure Migrate project
$MigrateJob =  New-AzMigrateServerReplication -InputObject $DiscoveredServer -TargetResourceGroupId $TargetResourceGroup.ResourceId -TargetNetworkId $TargetVirtualNetwork.Id -LicenseType NoLicenseType -OSDiskID $DiscoveredServer.Disk[0].Uuid -TargetSubnetName $TargetVirtualNetwork.Subnets[0].Name -DiskType Standard_LRS -TargetVMName MyMigratedTestVM -TargetVMSize Standard_DS2_v2

# Track job status to check for completion
while (($MigrateJob.State -eq 'InProgress') -or ($MigrateJob.State -eq 'NotStarted')){
        #If the job hasn't completed, sleep for 10 seconds before checking the job status again
        sleep 10;
        $MigrateJob = Get-AzMigrateJob -InputObject $MigrateJob
}
#Check if the Job completed successfully. The updated job state of a successfully completed job should be "Succeeded".
Write-Output $MigrateJob.State

Replicate VMs with select disks

You can also selectively replicate the disks of the discovered VM by using the New-AzMigrateDiskMapping cmdlet and providing that as an input to the DiskToInclude parameter in the New-AzMigrateServerReplication cmdlet. You can also use the New-AzMigrateDiskMapping cmdlet to specify different target disk types for each individual disk to be replicated.

Specify values for the following parameters of the New-AzMigrateDiskMapping cmdlet:

  • DiskId: Specify the unique identifier for the disk to be migrated. The disk ID to be used is the UUID property for the disk retrieved by using the Get-AzMigrateDiscoveredServer cmdlet.
  • IsOSDisk: Specify true if the disk to be migrated is the OS disk of the VM. Otherwise, specify false.
  • DiskType: Specify the type of disk to be used in Azure.

In the following example, we replicate only two disks of the discovered VM. We specify the OS disk and use different disk types for each disk to be replicated. The cmdlet returns a job that can be tracked for monitoring the status of the operation.

# View disk details of the discovered server
Write-Output $DiscoveredServer.Disk

# Create a new disk mapping for the disks to be replicated
$DisksToReplicate = @()
$OSDisk = New-AzMigrateDiskMapping -DiskID $DiscoveredServer.Disk[0].Uuid -DiskType StandardSSD_LRS -IsOSDisk true
$DataDisk = New-AzMigrateDiskMapping -DiskID $DiscoveredServer.Disk[1].Uuid -DiskType Premium_LRS -IsOSDisk false

$DisksToReplicate += $OSDisk
$DisksToReplicate += $DataDisk

# Retrieve the resource group that you want to migrate to
$TargetResourceGroup = Get-AzResourceGroup -Name MyTargetResourceGroup

# Retrieve the Azure virtual network and subnet that you want to migrate to
$TargetVirtualNetwork = Get-AzVirtualNetwork -Name MyVirtualNetwork

# Start replication for the VM
$MigrateJob =  New-AzMigrateServerReplication -InputObject $DiscoveredServer -TargetResourceGroupId $TargetResourceGroup.ResourceId -TargetNetworkId $TargetVirtualNetwork.Id -LicenseType NoLicenseType -DiskToInclude $DisksToReplicate -TargetSubnetName $TargetVirtualNetwork.Subnets[0].Name -TargetVMName MyMigratedTestVM -TargetVMSize Standard_DS2_v2

# Track job status to check for completion
while (($MigrateJob.State -eq 'InProgress') -or ($MigrateJob.State -eq 'NotStarted')){
        #If the job hasn't completed, sleep for 10 seconds before checking the job status again
        sleep 10;
        $MigrateJob = Get-AzMigrateJob -InputObject $MigrateJob
}
# Check if the Job completed successfully. The updated job state of a successfully completed job should be "Succeeded".
Write-Output $MigrateJob.State

Monitor replication

Replication occurs in the following cases:

  • When the Start Replication job finishes successfully, the machines begin their initial replication to Azure.
  • During initial replication, a VM snapshot is created. Disk data from the snapshot is replicated to replica-managed disks in Azure.
  • After initial replication finishes, delta replication begins. Incremental changes to on-premises disks are periodically replicated to the replica disks in Azure.

Track the status of the replication by using the Get-AzMigrateServerReplication cmdlet.

# List replicating VMs and filter the result for selecting a replicating VM. This cmdlet will not return all properties of the replicating VM.
$ReplicatingServer = Get-AzMigrateServerReplication -ProjectName $MigrateProject.Name -ResourceGroupName $ResourceGroup.ResourceGroupName -MachineName MyTestVM

# Retrieve all properties of a replicating VM 
$ReplicatingServer = Get-AzMigrateServerReplication -TargetObjectID $ReplicatingServer.Id

You can track the Migration State and Migration State Description properties in the output.

  • For initial replication, the values for the Migration State and Migration State Description properties are InitialSeedingInProgress and Initial replication, respectively.
  • During delta replication, the values for the Migrate State and Migration State Description properties are Replicating and Ready to migrate, respectively.
  • After you finish the migration, the values for the Migrate State and Migration State Description properties are Migration succeeded and Migrated, respectively.

Replication occurs in the following cases:

  • When the Start Replication job finishes successfully, the machines begin their initial replication to Azure.
  • During initial replication, a VM snapshot is created. Disk data from the snapshot is replicated to replica-managed disks in Azure.
  • After initial replication finishes, delta replication begins. Incremental changes to on-premises disks are periodically replicated to the replica disks in Azure.

Retrieve the status of a job

You can monitor the status of a job by using the Get-AzMigrateJob cmdlet.

# Retrieve the updated status for a job
$job = Get-AzMigrateJob -InputObject $job

Update properties of a replicating VM

Migration and modernization allows you to change target properties, such as name, size, resource group, NIC configuration, and so on, for a replicating VM.

The following properties can be updated for a VM.

Parameter Type Description
VM name Optional Specify the name of the Azure VM to be created by using the TargetVMName parameter.
VM size Optional Specify the Azure VM size to be used for the replicating VM by using the TargetVMSize parameter. For instance, to migrate a VM to D2_v2 VM in Azure, specify the value for TargetVMSize as Standard_D2_v2.
Virtual network Optional Specify the ID of the Azure virtual network that the VM should be migrated to by using the TargetNetworkId parameter.
Resource group Optional IC configuration can be specified by using the New-AzMigrateNicMapping cmdlet. The object is then passed an input to the NicToUpdate parameter in the Set-AzMigrateServerReplication cmdlet.

- Change IP allocation: To specify a static IP for a NIC, provide the IPv4 address to be used as the static IP for the VM by using the TargetNicIP parameter. To dynamically assign an IP for a NIC, provide auto as the value for the TargetNicIP parameter.
- Use the values Primary, Secondary or DoNotCreate for the TargetNicSelectionType parameter to specify whether the NIC should be primary, secondary, or shouldn't be created on the migrated VM. Only one NIC can be specified as the primary NIC for the VM.
- To make a NIC primary, you also need to specify the other NICs that should be made secondary or aren't to be created on the migrated VM.
- To change the subnet for the NIC, specify the name of the subnet by using the TargetNicSubnet parameter.
Network interface Optional Specify the name of the Azure VM to be created by using the TargetVMName parameter.
Availability zone Optional To use availability zones, specify the availability zone value for the TargetAvailabilityZone parameter.
Availability set Optional To use availability sets, specify the availability set ID for the TargetAvailabilitySet parameter.
Tags Optional For updating tags, use the following parameters: UpdateTag or UpdateVMTag, UpdateDiskTag, UpdateNicTag, and type of update tag operation UpdateTagOperation or UpdateVMTagOperation, UpdateDiskTagOperation, UpdateNicTagOperation. The update tag operation takes the following values: Merge, Delete, and Replace.
Use UpdateTag to update all tags across VMs, disks, and NICs.
Use UpdateVMTag to update VM tags.
Use UpdateDiskTag to update disk tags.
Use UpdateNicTag to update NIC tags.
Use UpdateTagOperation to update the operation for all tags across VMs, disks, and NICs.
Use UpdateVMTagOperation to update VM tags.
Use UpdateDiskTagOperation to update disk tags.
Use UpdateNicTagOperation to update NIC tags.

The replace option replaces the entire set of existing tags with a new set.
The merge option allows adding tags with new names and updating the values of tags with existing names.
The delete option allows selectively deleting tags based on specific names or name/value pairs.
Disks Optional For the OS disk:
- Update the name of the OS disk by using the TargetDiskName parameter.

To update multiple disks:
- Use Set-AzMigrateDiskMapping to set the disk names to a variable $DiskMapping. Then use the DiskToUpdate parameter and pass along the variable.

The disk ID to be used in Set-AzMigrateDiskMapping is the UUID property for the disk retrieved by using the Get-AzMigrateDiscoveredServer cmdlet.
NIC's name Optional Use New-AzMigrateNicMapping to set the NIC names to a variable $NICMapping. Then use the NICToUpdate parameter and pass the variable.

The Get-AzMigrateServerReplication cmdlet returns a job that can be tracked for monitoring the status of the operation.

# List replicating VMs and filter the result for selecting a replicating VM. This cmdlet will not return all properties of the replicating VM.
$ReplicatingServer = Get-AzMigrateServerReplication -ProjectName $MigrateProject.Name -ResourceGroupName $ResourceGroup.ResourceGroupName -MachineName MyTestVM

# Retrieve all properties of a replicating VM 
$ReplicatingServer = Get-AzMigrateServerReplication -TargetObjectID $ReplicatingServer.Id

# View NIC details of the replicating server
Write-Output $ReplicatingServer.ProviderSpecificDetail.VMNic

In the following example, we update the NIC configuration by making the first NIC as primary and assigning a static IP to it. We discard the second NIC for migration, update the target VM name and size, and customize NIC names.

# Specify the NIC properties to be updated for a replicating VM.
$NicMapping = @()
$NicMapping1 = New-AzMigrateNicMapping -NicId $ReplicatingServer.ProviderSpecificDetail.VMNic[0].NicId -TargetNicIP ###.###.###.### -TargetNicSelectionType Primary TargetNicName "ContosoNic_1"
$NicMapping2 = New-AzMigrateNicMapping -NicId $ReplicatingServer.ProviderSpecificDetail.VMNic[1].NicId -TargetNicSelectionType DoNotCreate - TargetNicName "ContosoNic_2"

$NicMapping += $NicMapping1
$NicMapping += $NicMapping2

# Update the name, size and NIC configuration of a replicating server
$UpdateJob = Set-AzMigrateServerReplication -InputObject $ReplicatingServer -TargetVMSize Standard_DS13_v2 -TargetVMName MyMigratedVM -NicToUpdate $NicMapping

In the following example, we customize the disk name.

# Customize the Disk names for a replicating VM
$OSDisk = Set-AzMigrateDiskMapping -DiskID "6000C294-1217-dec3-bc18-81f117220424" -DiskName "ContosoDisk_1" 
$DataDisk1= Set-AzMigrateDiskMapping -DiskID "6000C292-79b9-bbdc-fb8a-f1fa8dbeff84" -DiskName "ContosoDisk_2" 
$DiskMapping = $OSDisk, $DataDisk1 

# Update the disk names for a replicating server
$UpdateJob = Set-AzMigrateServerReplication InputObject $ReplicatingServer DiskToUpdate $DiskMapping

In the following example, we add tags to the replicating VMs.

# Update all tags across virtual machines, disks, and NICs.
Set-azmigrateserverreplication UpdateTag $UpdateTag UpdateTagOperation Merge/Replace/Delete

# Update virtual machines tags
Set-azmigrateserverreplication UpdateVMTag $UpdateVMTag UpdateVMTagOperation Merge/Replace/Delete

Use the following example to track the job status.

# Track job status to check for completion
while (($UpdateJob.State -eq 'InProgress') -or ($UpdateJob.State -eq 'NotStarted')){
        #If the job hasn't completed, sleep for 10 seconds before checking the job status again
        sleep 10;
        $UpdateJob = Get-AzMigrateJob -InputObject $UpdateJob
}
# Check if the Job completed successfully. The updated job state of a successfully completed job should be "Succeeded".
Write-Output $UpdateJob.State

Run a test migration

When delta replication begins, you can run a test migration for the VMs before you run a full migration to Azure. We highly recommend that you do test migration at least once for each machine before you migrate it. The cmdlet returns a job that can be tracked for monitoring the status of the operation.

  • Running a test migration checks that migration works as expected. Test migration doesn't affect the on-premises machine, which remains operational and continues replicating.
  • Test migration simulates the migration by creating an Azure VM by using replicated data. The test usually migrates to a nonproduction virtual network in your Azure subscription.
  • You can use the replicated test Azure VM to validate the migration, perform app testing, and address any issues before full migration.

Select the Azure virtual network to be used for testing by specifying the ID of the virtual network by using the TestNetworkID parameter.

# Retrieve the Azure virtual network created for testing
$TestVirtualNetwork = Get-AzVirtualNetwork -Name MyTestVirtualNetwork

# Start test migration for a replicating server
$TestMigrationJob = Start-AzMigrateTestMigration -InputObject $ReplicatingServer -TestNetworkID $TestVirtualNetwork.Id

# Track job status to check for completion
while (($TestMigrationJob.State -eq 'InProgress') -or ($TestMigrationJob.State -eq 'NotStarted')){
        #If the job hasn't completed, sleep for 10 seconds before checking the job status again
        sleep 10;
        $TestMigrationJob = Get-AzMigrateJob -InputObject $TestMigrationJob
}
# Check if the Job completed successfully. The updated job state of a successfully completed job should be "Succeeded".
Write-Output $TestMigrationJob.State

After testing is complete, clean up the test migration by using the Start-AzMigrateTestMigrationCleanup cmdlet. The cmdlet returns a job that can be tracked for monitoring the status of the operation.

# Clean-up test migration for a replicating server
$CleanupTestMigrationJob = Start-AzMigrateTestMigrationCleanup -InputObject $ReplicatingServer

# Track job status to check for completion
while (($CleanupTestMigrationJob.State -eq "InProgress") -or ($CleanupTestMigrationJob.State -eq "NotStarted")){
        #If the job hasn't completed, sleep for 10 seconds before checking the job status again
        sleep 10;
        $CleanupTestMigrationJob = Get-AzMigrateJob -InputObject $CleanupTestMigrationJob
}
# Check if the Job completed successfully. The updated job state of a successfully completed job should be "Succeeded".
Write-Output $CleanupTestMigrationJob.State

Migrate VMs

After you verify that the test migration works as expected, you can migrate the replicating server by using the following cmdlet. The cmdlet returns a job that can be tracked for monitoring the status of the operation.

If you don't want to turn off the source server, don't use the TurnOffSourceServer parameter.

# Start migration for a replicating server and turn off source server as part of migration
$MigrateJob = Start-AzMigrateServerMigration -InputObject $ReplicatingServer -TurnOffSourceServer

# Track job status to check for completion
while (($MigrateJob.State -eq 'InProgress') -or ($MigrateJob.State -eq 'NotStarted')){
        #If the job hasn't completed, sleep for 10 seconds before checking the job status again
        sleep 10;
        $MigrateJob = Get-AzMigrateJob -InputObject $MigrateJob
}
#Check if the Job completed successfully. The updated job state of a successfully completed job should be "Succeeded".
Write-Output $MigrateJob.State

Complete the migration

  1. After the migration is finished, stop replication for the on-premises machine and clean up replication state information for the VM by using the following cmdlet. The cmdlet returns a job that can be tracked for monitoring the status of the operation.

    # Stop replication for a migrated server
$StopReplicationJob = Remove-AzMigrateServerReplication -InputObject $ReplicatingServer

    # Track job status to check for completion
while (($StopReplicationJob.State -eq 'InProgress') -or ($StopReplicationJob.State -eq 'NotStarted')){
        #If the job hasn't completed, sleep for 10 seconds before checking the job status again
        sleep 10;
        $StopReplicationJob = Get-AzMigrateJob -InputObject $StopReplicationJob
}
# Check if the Job completed successfully. The updated job state of a successfully completed job should be "Succeeded".
Write-Output $StopReplicationJob.State

  2. Perform any post-migration app tweaks, such as updating database connection strings, and web server configurations.

  3. Perform final application and migration acceptance testing on the migrated application now running in Azure.

  4. Cut over traffic to the migrated Azure VM instance.

  5. Remove the on-premises VMs from your local VM inventory.

  6. Remove the on-premises VMs from local backups.

  7. Update any internal documentation to show the new location and IP address of the Azure VMs.
