Just wondering about the upgrade process and if there's any thing i ned to fear being broken on FC4 considering i just got everything set up the way i want it? And what is the upgrade process?
Assuming the your current install works 100%, there is no fear in upgrade. I have wondered myself in the past. The upgrade will look and feal like a new install, so dont worry. The installed is smart enough to know that it is upgrading from 2.07. You will have to re-enter the SSL information also.
The upgrade process recognizes older ISPConfig versions on your server and makes an upgrade instead of a new installation. This does not change anything in your linux configuration.
