Quick followup. After failing to find a burning program that would let me burn at 8x speed I burned it at my burner's lowest setting 16x and tried it out on one of my remaining good CASes. The upgrade went fine for that CAS and for the CAM. I now get to clean up the mess from the first disk. Michael

Rebooted again with install disk and was no longer given an option to upgrade only fresh install. I was told by support that this was probably caused by not burning my CD at 8x speed? I'm now supposed to fresh install these boxes and hope the config is not lost when I get them back into the CAM. I also need to find a burning program that will burn at less than 16x since mine does not. >>> "Heller, Josh" <hel...@kutztown.edu> 11/25/2009 10:55 AM >>> Greetings, The Release Notes indicate that the installer will prompt you for whether you would like to perform an upgrade or a fresh install. This is provided that you gracefully shutdown each appliance before booting off of the 4.7.1 CD. That command is noted as being “shutdown –r now”.

Josh, Does that mean we need to do a fresh install on the CAS and CAM if they are running 4.6.1? And if so, I assume there any way to import the config and certs from my existing deployment right? Has anyone out there done this with success??

I sure do hope that they return to “upgrade” packages going forward. They were much more convenient than the CD based process we’ll need to go through to upgrade to 4.7.1.
