Trying to upgrade our ePO server from 4.5 Patch 4 to 4.6 Patch 7 and I'm getting a consistent failure each time shortly after trying to start new services. I can recover from it using the following method:
Any ideas why I'm having this consistent failure on first attempt? There's nothing in the install logs that points to anything specific.
It's an absolute pain to have to upgrade using this method and it's not going to swing with management if that's the way we have to do it!!
Found the problem!
The 8.3 was a bit of a red herring. The problem was a simple port conflict between the installer and the McAFee Framework Service.
As soon as I stop and disable the Framework Service the install goes through without any issues at all.
