Migrating from On-Premises VDI to Azure Virtual Desktop: What You Need to Know

In today’s world, businesses are increasingly shifting towards cloud-based solutions for scalability, flexibility, and cost-efficiency. One area where this is particularly evident is in virtual desktop infrastructure (VDI). For many organizations, on-premises VDI has been a go-to solution for providing remote access to desktops. However, with the rise of cloud technologies and the growing popularity of Microsoft’s Azure Virtual Desktop (AVD), many businesses are considering a move to the cloud. Migrating from an on-premises VDI environment to Azure Virtual Desktop may seem like a daunting task, but with the right planning and execution, it can significantly improve your organization’s efficiency, security, and scalability. In this blog, we will walk you through the key steps and considerations for a successful migration to Azure Virtual Desktop.

Why Migrate to Azure Virtual Desktop?

Before diving into the migration process, it’s important to understand the benefits of making the switch from on-premises VDI to Azure Virtual Desktop. Here are a few reasons why organizations are making the move:

1. Scalability: Azure Virtual Desktop allows you to easily scale up or down based on demand. Whether you’re accommodating temporary seasonal workers or expanding your team, AVD makes it easier to adjust resources.
2. Cost-Effectiveness: By moving to the cloud, you eliminate the need for expensive on-premises hardware, reducing both capital expenditures and ongoing maintenance costs.
3. Security: With Azure’s built-in security features like multi-factor authentication (MFA), role-based access control (RBAC), and encryption, your data remains safe and secure. Additionally, the responsibility for patching and updates is handled by Microsoft, ensuring your environment is always up to date.
4. Flexibility: Azure Virtual Desktop offers users the flexibility to access their desktops and applications from anywhere on any device, which is ideal for remote work and hybrid work environments.
5. Seamless Integration with Microsoft 365: AVD integrates effortlessly with Microsoft’s suite of productivity tools, including Office 365, Teams, OneDrive, and others, making it easier to maintain continuity in your workflows.

Key Considerations Before Migrating

Migrating from an on-premises VDI environment to Azure Virtual Desktop is not a one-size-fits-all approach. All organization’s requirements are different, so it’s important to carefully plan the migration to ensure a smooth transition. Here are some key considerations to keep in mind:

1. Assess Your Current Environment
Before you begin the migration process, it’s crucial to assess your current on-premises VDI environment. Evaluate the following:

• User profiles and applications: Identify which applications and user profiles will be migrated to the cloud and ensure compatibility with AVD.
• Licensing: Check your current licensing arrangements for VDI and determine how they will translate to Azure Virtual Desktop. You may need to update your licensing or purchase new plans.
• Infrastructure: Understand the specifications of your on-premises hardware and compare them with Azure’s available virtual machine (VM) types and configurations.

2. Define Your Migration Strategy
There are several strategies for migrating to Azure Virtual Desktop:

• Lift-and-shift: This approach involves moving your existing VDI setup to AVD with minimal changes. It is the fastest approach but may not take full advantage of Azure’s scalability and other cloud-native features.
• Rebuild: In this strategy, you rebuild your environment from scratch on Azure, optimizing for cloud-native features such as autoscaling, load balancing, and Azure-based storage.
• Hybrid approach: A hybrid strategy involves running your VDI environment both on-premises and in the cloud for a period, allowing you to gradually transition and test before fully migrating to the cloud.

3. Network and Connectivity
Ensure that your network is prepared to handle the increased demand for cloud resources. AVD requires a reliable and fast internet connection, so you should:

• Evaluate your bandwidth and latency to ensure that users will experience smooth, lag-free access to their virtual desktops.
• Consider using Azure’s ExpressRoute or VPN Gateway for secure and reliable connectivity between your on-premises environment and Azure.
• Assess how to optimize the user experience, especially for remote locations or remote workers.

4. User Experience and Desktop Configuration
One of the biggest challenges when migrating to Azure Virtual Desktop is ensuring that the end-user experience is as smooth as possible. Here are some key considerations:

• User profiles: Migrate your users’ profiles and data to the cloud. This may involve using tools like FSLogix to manage user profiles in a non-persistent desktop environment.
• App delivery: Decide how to deliver applications to users in the AVD environment. You can either deliver full desktops (e.g., Windows 10 or 11 multi-session) or individual apps (e.g., Microsoft Office, legacy apps).
• Custom configurations: If you’re on-premises VDI had custom configurations, such as group policies or specific network drives, ensure these are replicated in your AVD

Step-by-Step Migration Process

1. Prepare Your Azure Environment

• Create a virtual network (VNet): Set up the network infrastructure in Azure, including VNets, subnets, and Network Security Groups (NSGs), to ensure proper communication and security between your virtual machines and users.
• Create a host pool: In AVD, a host pool is a collection of virtual machines that users can connect to. You’ll need to create a host pool and assign the correct virtual machine sizes and configurations.
• Set up FSLogix: Use FSLogix to manage user profiles and ensure that user data persists across sessions in a non-persistent environment.

2. Migrate Applications and Data

• Install applications: Install and configure the necessary applications on your virtual machines within the host pool.
• Move data: If your users’ data is stored locally, you may want to move it to a centralized storage solution like Azure Files or OneDrive to make it accessible across different devices.

3. Test and Validate the Environment

Before migrating all users to Azure Virtual Desktop, perform a pilot migration. Select a small group of users to test the system, check performance, and ensure that all applications and services function as expected.

4. Cutover and User Migration

After successful testing, you can begin migrating users to the Azure environment. Make sure to communicate the migration schedule to users and provide support during the transition.

5. Ongoing Management and Optimization

Once the migration is complete, you will need to monitor the environment and optimize performance. Azure offers tools like Azure Monitor and Azure Advisor to help with monitoring, reporting, and optimizing resource usage.

Conclusion

Migrating from an on-premises VDI environment to Azure Virtual Desktop is a significant shift, but the benefits—such as cost savings, scalability, security, and flexibility—are well worth the effort. By carefully planning and following a structured migration approach, you can ensure a smooth transition that enhances the overall productivity and experience for your users. Remember, the key to a successful migration lies in thoroughly understanding your current environment, defining clear goals, and continuously optimizing the cloud infrastructure post-migration. With Azure Virtual Desktop, the future of remote work is at your fingertips, and the cloud is the key to unlocking its full potential.
