Hi @Jeremy Robertson

If you have already verified that the authentication settings on both the source and target servers match, you may want to check if the target server is added to the list of servers that are allowed to delegate credentials. You can do this by opening Active Directory Users and Computers, selecting the computer object for the target server, and checking the "Trust this computer for delegation to specified services only" option.

If the issue persists, you may need to check if there are any firewalls or network security groups that are blocking the migration traffic.

Hope the information is helpful.

Hey,

There are multiple reasons why Live Migration can fail. As an additional troubleshooting, you can try verifying network connectivity. Ensure both hosts can communicate over the network on the required ports. If there are any firewall rules blocking migration traffic, this can prevent credential verification. Check that your antivirus doesn't block traffic.

You can also try to disable and re-enable Live Migration. Might be helpful: https://www.makeuseof.com/hyper-v-error-0x8009030e-windows/

As another option, StarWind V2V Converter can be used to migrate VMs between Hyper-V hosts.
