Both VMware and Microsoft Hyper-V are reliable hardware virtualization platforms. However, each has its unique features and purposes. And sometimes, organizations might need to convert a Hyper-V VM (virtual machine) to VMware. And what you must know that is, migrating a Hyper-V-based VM to VMware is simple but not easy, as there are some strategies that make this process simpler.
In this guide, we will give step-by-step instructions to make a successful transition between these hardware virtualization platforms.
Preparation Before Migration
To ensure a smooth and error-free conversion, it is crucial to take a few preparatory steps.
Evaluating the Current VM State: Ensuring the VM is in Good Shape and Checking for Possible Issues
Before attempting to migrate, ensure that the Hyper-V-based VM you are migrating is in good shape. In particular:
- Empty the trash bin.
- Run the disk cleanup wizard.
- It is also wise to defragment the disk.
- You can also check for any virtual devices, such as serial ports or CDs attached to the VM, and ensure to detach them.
- Check and verify that DNS resolution is working properly.
- And all the involved hosts can be pinged — to avoid frequent issues that might cause migration failure.
Additionally, stop the nonessential services and all the work that is being performed.
Installing the Necessary Tools: Detailing the Installation of the VMware Converter Tool
The next essential step is installing the VMware converter tool. This tool acts as the management station for the Hyper-V to VMware migration. For this:
- Download the VMware converter tool and follow the default options during the installation process.
It is advisable to install the converter onto a stable jump host. This is to avoid any unexpected reboots during the process.
These preparatory steps help you lay a strong foundation for a successful Hyper-V to VMware migration. And ensures to avoid any unexpected issues during the process.
Follow along to learn how to convert Hyper-V to VMware.
Step-by-Step Hyper-V to VMware Conversion Process
Note: The steps may vary slightly depending on the exact versions of Hyper-V and VMware being used, and the unique configurations. So, this guide gives you a good introduction and makes you aware of the conversion process. But it is best to consult the relevant official documentation and have a qualified IT professional familiar with your specific setup to ensure a smooth migration from Hyper-V to VMware.
Step 1. Instructions to Begin the Conversion Process
- Launch the VMware converter tool.
- Once the tool is open, choose “Convert Machine” from the top menu options.
- Choose “Powered-off” as the source type if the VM is off. Or choose “Powered-on” if it’s running.
- And from the drop-down menu, choose Hyper-V as the source and provide the Hyper-V host’s credentials.
Step 2. Set Up the Source Hyper-V Machine and Destination VMware Infrastructure
You have to provide the necessary details like IP address, username, and password. After filling in the details:
- Configure the destination by selecting the VMware infrastructure as the destination type.
- Enter the credentials for the VMware host or vCenter.
- Select the destination datastore where the VM will be hosted.
Click “Next” to continue.
Step 3. Deploy VMware vCenter Standalone Agent
On the next screen, you will see a pop-up window for temporary installation of the agent on the Hyper-V Server.
- Select the desired method to uninstall the agent after conversion and wait for deployment.
Step 4. Choose Source Machine
Choose the desired VM you want to convert from the list of virtual machines. And click “Next.”
Step 5. Set Destination System
- Choose “VMware Infrastructure virtual machine” if you want a VM running on an ESXi host (as shown here).
- Enter the necessary details of the vCenter Server or the standalone ESXi host.
- And click “Next.”
Step 6. Set Parameters for Destination VM
- Choose the name, location, and other parameters for the VM and select “Next.”
Step 7. Choose Location for Destination VM
- Choose the ESXi host, datastore, and VM version. Click “Next.”
Step 8. Configure Conversion Task Parameters
For this:
- Choose the data to copy — select disk or volume-based copy, provisioning type, and destination datastore.
- Choose the devices — set memory, processors, disk controller, etc.
- Select the networks — Configure virtual network adapters.
- Then services & advanced options — Windows OS machines related configurations.
- Throttling — control CPU and network bandwidth usage during conversion.
If you are using a thin disk type by default, follow the additional instructions provided in the source text.
Step 9. Review the Summary and Start Conversion
Review all the settings and if everything looks correct — select “Finish” to start the conversion. You can monitor the conversion status in the main menu of the converter.
Once the conversion is complete, start the VM using VMware vSphere Client, VMware vSphere Web Client, VMware Host Client, VMware Workstation, or PowerCLI.
Additional Tips and Strategies
1. Exploring CPU and Network Throttling
- CPU Throttling: This option allows you to control how much CPU is used during the conversion, so you can run other tasks and save CPU resources.
- Network Throttling: This option allows you to limit the network bandwidth used during the conversion, so you can manage other network services running on the server.
2. How to Set Thin-Provisioned Disks as Default
Thin-Provisioned Disks uses space only as per need and saves storage.
- To set thin-provisioned disks as default, edit the converter-worker.xml file.
- Change the false value to true in the <preferThinDiskType> tag.
You can use Advanced Options to get insights into options like Synchronizing Changes and Installing VMware Tools.
3. Customize the Guest Preferences to tweak the OS and applications to match the new environment.
These three additional tweaks help you add flexibility and efficiency to the conversion process.
Conclusion
Converting Hyper-V VMs to VMware is not a difficult process. However, it does demand careful planning and following the right strategy. And this guide aims to do that, so you can make the process as smooth as possible for your Hyper-V to VMware migration journey. By following the instructions carefully, you can make a successful transition between these hardware virtualization platforms.
