We have an existing Metaframe XPe farm. We are going to build a new CPS 4.0 farm to replace it. I need to perform the license upgrade on mycitrix.com. Will doing this cause a problem with my old Metaframe XPe farm? It's critical that it stays up and operational while I pre-stage the replacement farm. Also, Will NFuse 1.7 work w/ CPS 4.0 or will I need to upgrade the web piece at the same time? Thanks, MM
