Update WorkflowID in workflow.ChildWorkflowOptions{..}

I am working on a temporal workflow with a few child workflows. I want to update WorkflowID of one of the child workflows while workflows are running.

func (w Workflow) ParentWorkflow(ctx workflow.Context, parentWorkflowRequest models.ParentWorkflowRequest) error {
...
cwo := workflow.ChildWorkflowOptions{
		WorkflowTaskTimeout: time.Minute,
	}
childctx := workflow.WithChildOptions(ctx, cwo)
	err = workflow.ExecuteChildWorkflow(childctx, w.ChildWorkflow, childWorkflowRequest).Get(childctx, nil)
	if err != nil {
		return err
	}

I want change ChildWorkflowOptions from

cwo := workflow.ChildWorkflowOptions{
		WorkflowTaskTimeout: time.Minute,
	}

to

cwo := workflow.ChildWorkflowOptions{
		WorkflowTaskTimeout: time.Minute,
		WorkflowID:          GetChildWorkflowID("hostname"),
	}

I see after changes, workflow fails with following error:

A non-deterministic error has caused the Workflow Task to fail. This usually means the workflow code has a non-backward compatible change without a proper versioning branch.

Can we handle this change with versoning? I do not see a guide or example for workflow option updates that could be supported with versioning.

v := workflow.GetVersion(ctx, "options", workflow.DefaultVersion, 1)
if v == workflow.DefaultVersion {
        cwo = workflow.ChildWorkflowOptions{
		WorkflowTaskTimeout: time.Minute,
	}
} else {
       cwo = workflow.ChildWorkflowOptions{
		WorkflowTaskTimeout: time.Minute,
		WorkflowID:          GetChildWorkflowID("hostname"),
	}
}

Thank you. Will try this out.
