How to change environment while protecting documents using Experience Manager in Adobe Pro DC



I want to secure a document using Adobe Experience Manager in Adobe Acrobat Pro DC, and my policies are created in different environments. But once I have protected a document using policy from any one environment, I am not able to switch to any other server/location. Once we had set up to do the document securing in one environment (say Stage environment), I could not figure out how to add the another (say Production) environment. Would anyone have instructions for accomplishing that?

Thank you so much!
