Before removing your old cluster, save the as-built data. Then swap clusters and do the same with your new one. Then upload and write the PIU data into the new cluster. You can then go in to the non-asbuilt configuration and try turning things off and on as you would like. Just do one or two things at a time though or else you may find yourself unable to track down bugs as they pop up. The only reason you want to backup the new cluster before writing the PIU is in case you decided to get rid of it and sell it you can reupload the original asbuilt. Hope this helps.
