Step-by-Step Guide: How to Move Azure VM to a different Resource Group? (PowerShell Guide)

There are occasions where we need to move Azure Virtual Machines from one resource group to another. In this post, I am going to demonstrate how we can do that. Before start, there are a few things we should look in to.

• Not every resource can move from one resource group to another. More info about it can find under https://docs.microsoft.com/en-gb/azure/azure-resource-manager/move-support-resources

• If you are looking to move from one region to another, there is a separate process for that. I already wrote an article about it. You can access it using, https://www.rebeladmin.com/2019/11/step-step-guide-move-azure-vm-one-region-another/

• When you move resources, make sure to migrate all dependencies with it. 

• When a virtual machine is moved from one resource group to another, the system creates a new resource ID. If you use this value on scripts or other services, those will need to update after the move. 

• The same method also can use to move resources from one subscription to another. 

In this demo, I am going to create a new VM in one resource group and then move it to another.  

For the configuration process, I will be using PowerShell. Therefore, please make sure you have an Azure PowerShell module installed. More info about it can find under https://docs.microsoft.com/en-us/powershell/azure/install-az-ps?view=azps-2.6.0

1. Launch PowerShell console and connect to Azure using Connect-AzAccount

2. Then create two new resource group using,

New-AzResourceGroup -Name REBELRG1 -Location "East US"

New-AzResourceGroup -Name REBELRG2 -Location "East US"

In the above, REBELRG1 & REBELRG2 are the resource group names and East US is the resource group location.

3. The next step is to create a new virtual network under REBELRG1 resource group.

$vmsubnet  = New-AzVirtualNetworkSubnetConfig -Name vmsubnet -AddressPrefix "10.0.2.0/24"

New-AzVirtualNetwork -Name REBELVN1 -ResourceGroupName REBELRG1 -Location "East US" -AddressPrefix "10.0.0.0/16" -Subnet $vmsubnet

In the above, REBELVN1 is the new virtual network name. It has 10.0.0.0/16 address space. It also has a new subnet 10.0.2.0/24 (vmsubnet) for virtual machines. [Read more…] about Step-by-Step Guide: How to Move Azure VM to a different Resource Group? (PowerShell Guide)

Step-by-Step Guide to setup Azure VNet-to-VNet VPN Gateway Connection (PowerShell Guide)

If we need to set up a connection between two independent networks (not between VLANs), we have to use a virtual private network (VPN) connections. In Azure, we use VNets to create private networks. If we need to communicate between two VNets, we have to use one of the following methods,

• VNet-to-VNet Connection – The communication happens between two VPN gateways. This is easy to set up, compare to the site-to-site VPN method.

• Site-to-Site VPN – This is similar to creating VPN connection to the on-premises network. It also uses VPN gateway, but it gives more control over the local network gateway. 

• VNet Peering – This method doesn't use VPN gateways and it routes the traffic via Microsoft backend infrastructure. More information about VNet peering is available on https://docs.microsoft.com/en-us/azure/virtual-network/virtual-network-peering-overview

In this demo, I am going to demonstrate how to create a VNet-to-VNet connection. These types of connections can establish between,

• Virtual Networks in the same region

• Virtual Networks in different regions

• Virtual Networks in different subscriptions

In this demo, I am going to create a VNet-to-VNet VPN connection between two virtual networks in two different regions. 

According to the above diagram, EUSVnet1 virtual network will be running on East US Azure region and UKSVnet1 virtual network will be running on UK South Azure region. Let's see how we can establish a VPN gateway connection between these two networks. Before start, please make sure you have the following in place. 

• Valid Azure Subscription – You can also use free azure subscription for testing purpose. https://azure.microsoft.com/en-gb/free/ 

• Azure PowerShell Module – In this demo I am going to use PowerShell. Please make sure you have Azure PowerShell module installed. More info about it can find under https://docs.microsoft.com/en-us/powershell/azure/install-az-ps?view=azps-2.6.0

Create Resource Groups

The first step of the configuration is to create new resource groups in different regions. 

To do that, 

1. Launch PowerShell console and connect to Azure using Connect-AzAccount

2. Then create EUSRG1 under East US Azure region by using,

New-AzResourceGroup -Name EUSRG1 -Location "East US" 

In the above command, -Name parameter specifies the resource group name and -Location parameter specify the Azure region. 

3. Next step is to create UKSRG1 resource group in UK South Azure region by using,

New-AzResourceGroup -Name UKSRG1 -Location "UK South"
