Azure Migrate – How to migrate VMware workloads to Azure
PART 1 – Migration Planning and Migration Assessment
Migrating Production workloads is a big task. One that requires planning and consideration.
First ask yourself:
Who is moving to Azure?
What do you want to take with you?
Where are you going to in Azure?
What is driving the move?
Planning Planning Planning. It is so important. You cannot just lift and shift workloads into Azure, technically you can, but professionally it is a bad idea. Azure is expensive, and if you lift and shift, your costs will be extortionate.
You need to work out:
What can be migrated in its current state?
What can be re-architected? (for example, transform a Web Server to a Web App)
What will not migrate? there is always one server, physical appliance, or something that will cause you major headaches.
The Microsoft Migration Plan
- Strategy – define what success looks like including both business and technical goals
- Planning – map out what needs to be migrated, and how the strategy will be achieved
- Preparation – prepare both the source and the destination for the migration
- Migration – replicate servers from the source to the destination, perform a cutover
- Handover – handover the final solution to the operations team for ongoing maintenance
Azure Migrate Planning and Assessment
Azure migrate is the product used to migrate HyperV, VMware, Physical, and Other Cloud servers into Azure. Each migration must have a project, you can either have one big project with everything in it, or as I prefer, have multiple projects broken down to VMware, Hyper, and Physical
Step 1 – Create an Azure Migrate Project
First thing you need to do is:
Create is an Azure migrate project
Set up your migration tools.
- Open the Azure Portal and search for the Azure Migrate blade
- On the Azure Migrate blade, find the Servers button underneath the Migration Goals menu
IMPORTANT: providing you haven’t dabbled with Azure Migrate before, the servers area should be blank. If you have stuff in there, press the change button at the top right next to migrate project
- On the next menu Settings, locate the click here button to create a new project.
On the next page:
- Select Your Subscription
- Select or Create a New Resource Group
- Give your project a name
- Set the Geography
- On the select assessment tool tab – choose your assessment product, in this article I will be using Azure Migrate: Server Assessment
- On the select migration tool tab – choose your migration product, in this article I will be using Azure Migrate: Server Migration
- On the review tab click the Add Tools button to deploy your config to Azure Migrate
Step 2 – Server Assessment discovery process
The discovery tool will log all the metadata about your VMware installation. It can also provide cost and readiness data, and assess your infrastructure dependencies.
- Click the discover button on Azure Migrate: Server Assessment
On the Discover Machine menu
- Set Are you machines virtulized to Yes, with VMware vSphere Hypervisor
- Give you appliance a name on Name your Appliance
- Generate a Key
- Download the OVA package
- Install the OVA on your VMWare vCenter estate (I will assume you already know how to do this)
Step 3 – Configure the Azure Migrate Assessment Appliance
- Boot the VMware Appliance you have installed via the OVF
- Log into the remote console
- Set the servers local Administrator password
- Give the server and IP Address, Subnet and Gateway
- Launch the Appliance Configuration Manager, it should launch automatically, if not there is a shortcut on the desktop
- The appliance will run through some inital checks
- As per the picture above, I needed to install the VMware Virtual Disk Dev kit. Simply click the download link, log in to VMware.com, download, and copy the files into C:\Program Files\VMWare\VMware Virtual Disk Development Kit\
- Once completed click the verify button
- Next copy the Project Key that was created in Step 2 and click LOGIN
- You will be prompted for you Azure Credentials and password to link to PowerShell CLI on the appliance
Note: You MUST have an account that has permissions to create an Azure AD App
- When the Appliance Registration process has finished, the Add Credentials button will become active
Set the following
- Set Source Type as: vCenter Server
- Set friendly name as anything you want
- Set the Username and Password
Note: The account must have root access to vCenter. I will be using the default Administrator account
Note: You may need to refresh the webpage to get the change to pick up
- Next, click the Add Discovery Source – enter your details (this is your vCenter Server Appliance IP Address)
- Next, click the Add Credentials button. I will add my Linux sudo root account for ansible, this is because it is already configured on the estate
- Next, Click the Start Discovery button
- Upon completition you will see this message
That’s it, go to your DISCOVERED ITEMS in Azure migrate and your data will be available
