3. If a VM is found in the VM Overrides entries, check the corresponding vSphere DRS automation level. It is "Disabled" or "Manual," which is preventing DRS from automatically migrating the VM. Check if the VM entry can be deleted.

5. If the entry cannot be deleted, set the DRS automation level for the VM to "Fully Automated." This enables DRS to automatically migrate the VM.
