Moving Workfront Proofing Stages

I have a request to change an existing Workfront proofing workflow. They want to switch the first and second stages. I didn't see a way to do that. Does anyone know if that is possible and if so, how to do it?

I was thinking about creating a new stage and then deleting the existing first stage. Would that affect any existing proofs that used this workflow?

Any other suggestions on how to accomplish this?
