You are right, but I was a little bit stone, all the same using a local package, the installation duration was such a long... 3 to 5 hours in 7.0 ! The download part, is not significant according mass script DB building process.
I plan my consulting to start install before 12h, go lunch, make briefing meeting just after, architecture review & validation with customer, so the 4 hours installation was over, when coming back around 16pm, to setup initial settings.
After Symantec EPM Field Enablement meeting @Ratingen in february, we receive the Symantec information they are thinking about accelerating the setup, using a blank DB instead of the mass scripting from scratch building, as currently.
