Live Migrating Guest VMs from Hyper-V 2016 to 2022

Question

Hi there,

We currently have a Windows 2016 Hyper-V cluster with two servers and shared storage.

We plan to replace the existing infrastructure with two new servers and new shared storage.

Questions:

1. Can I directly live migrate the guest VMs from the existing cluster to the new cluster using Hyper-V Manager?
2. Or should I perform a two-step migration, first from 2016 to 2019, and then from 2019 to 2022?

Thanks for your advice.

Answer 1

Hi Albert,

Thanks for your post. Regarding the question 1, we do not recommend the live migration from cluster 2016 to 2022. There are some prerequisites for the upgrade. Complete the following requirements before you begin the Cluster OS Rolling Upgrade process: Verify that the Hyper-V nodes have CPUs that support Second-Level Addressing Table (SLAT) using one of the following methods; - Review the Are you SLAT Compatible? WP8 SDK Tip 01 article that describes two methods to check if a CPU supports SLATs - Download the Coreinfo v3.31 tool to determine if a CPU supports SLAT.

Also, refer the following article for the workflow.

2. You should perform a two-step migration, first from 2016 to 2019, and then from 2019 to 2022. Start with a Failover Cluster running Windows Server 2012 R2 or newer. You can upgrade to the next version, for example from Windows Server 2016 to Windows Server 2019.
