I recently decommissioned an older system (5.2). It's now going to be used as a lab system. As far as I can tell, the only thing I need to be careful about is making sure the same IPSI/SIPI used to generate the RFA license is used. Can I change IP addresses of the S8400, CMM, SIPI/IPSI, C-LAN, and Medpro cards without worry of invalidating the licenses?
