Upgrading From Windows Server 2012 to Windows Server 2022

If you are looking to upgrade from Windows Server 2012 to Windows Server 2022, you have a substantial jump in versions, and a direct in-place upgrade is not supported. As a result, you'll need to consider a migration approach.

Here's a detailed step-by-step guide on how to proceed:

1. Assess Your Current Environment:

  • Compatibility Check: Determine if your applications and services are compatible with Server 2022. You might need to check with the software vendors or test in a lab environment.

  • Hardware: Make sure your hardware meets the minimum requirements for Server 2022. It's possible that older hardware running Server 2012 may not be suitable for Server 2022.

2. Backup Everything:

  • Before you proceed with anything, take a full backup of your current server, including system state, application data, and configurations.

  • Make sure you test your backup to confirm you can restore from it in case of any issues.

3. Migration Approach:

Given that a direct in-place upgrade is not possible, you'll need to set up a new server with Windows Server 2022 and then migrate your roles, features, and data.

  • New Server Setup: Install Windows Server 2022 on a new server or virtual machine.

  • Role & Feature Migration: Depending on what roles and features you have on your 2012 server, you will need to install those roles/features on the new server and then migrate the data. For example:

    • Active Directory: Use tools like dcpromo or AD migration tools to replicate AD data.

    • File Services: You can use tools like Robocopy or the Storage Migration Service.

    • Other roles: Research and use best practices for migrating specific roles like DHCP, DNS, Print Services, etc.


  • Application Migration: For applications running on your Server 2012, you might need to reinstall them on Server 2022 and then migrate the data. Check with application vendors for best practices.

4. Testing:

  • After migrating roles, features, and applications, test thoroughly to ensure everything works as expected.

  • This might involve end-users or application owners testing functionalities and validating data.

5. Decommissioning the Old Server:

  • Once you're sure that everything has been migrated and is functioning correctly, you can consider decommissioning the old Server 2012.

  • It's typically a good practice to keep the old server running but isolated (offline) for a short period as an additional backup.

6. Post-migration Tasks:

  • Update any documentation to reflect the new server setup.

  • Monitor the new server's performance, errors, and other logs to ensure stability.

7. Licensing:

  • Ensure you have the appropriate licenses for Windows Server 2022. Also, check if any applications require new licenses due to the server upgrade.

Important Notes:

  • Plan and Document: Every step you take should be planned, and it's a good practice to document the entire process, including any issues faced and their solutions.

  • Deprecated Features: Some features available in Server 2012 might be deprecated in Server 2022. Review Microsoft's documentation to understand any changes that might affect your setup.

  • Seek Expertise: If you're unsure about the migration process, especially for critical applications or roles, consider seeking help from IT professionals experienced in Windows Server migrations.
