RM and Promote to Production and VNXe

The RM admin guide explain how to promote to production but doesn't clearly state how you clean up afterwards.

It says

1. unmask the promoted clone LUN using the Celerra Manager Interface

2. Use the server_iscsi command to make the replica read-only.

How can I do the equivalent for VNXe and can the documentation be updated to include VNXe procedures?

Look slike the only thing to do is delete the replica and recreate the relationship.

Thanks in advance for any suggestions.
