Source facts

\n

Microsoft distinguishes workgroup clustering, introduced earlier, from workgroup-cluster live migration support introduced with Windows Server 2025. The documented setup requires a running cluster of at least two nodes and matching local account names and passwords on the nodes. The cluster uses self-signed PKU2U certificates for movement between hosts rather than Kerberos in this workflow. Microsoft Learn.

\n

Applicability

\n

Confirm that the proposed hosts and cluster match the current support requirements. Identify the local-account lifecycle and the operators responsible for each node. Do not transfer assumptions from a domain-based constrained-delegation design into the workgroup procedure.

\n

DSE recommendation

\n

Have the virtualization and identity owners document how the required node accounts will be provisioned, protected, rotated, and removed. Keep credentials out of runbooks and ordinary evidence files. Select a representative VM and confirm its source and destination configuration before a pilot. Include a recovery management path if account consistency or the migration relationship fails.

\n

Verification

\n

Perform the approved live move and verify the VM’s resulting host and application behavior. Record the documented authentication configuration and any failed connection separately from storage or hardware compatibility issues. Check the operational procedure after an approved account-lifecycle exercise. Accept the workflow only when its local-account ownership is maintainable across every intended node.
