Upgrading from 4.1.3 to 4.7.2 and certs

[Bruce Hodge]

Hi, I am going to upgrade my NAC 3140 appliances from 4.1.3 to 4.7.2 and I just wanted to get some pointers, hints and traps for young players. I have been led to believe that the best option is to upgrade to 4.6.1 first and then upgrade to 4.7.2. The thing that I am really unsure about is the loss of the perfigo certificates , how that effects the upgrade process, and what is the best process to avoid having a busted NAC? I haven't done an upgrade on these for a long time and I am pretty green about certificates so any help would be appreciated.
