Can I just create a package for 11.0.5002.0 and distribute it to them for installation. Will the new package remove the old one without any issues and keep the previous exclusion zones?
--Yes , if you are installing it over SEP it will automatically upgrade and retain the settings but if you are installing over SAV , it will uninstall SAV and install SEP , but will not retain the settings
Is a restart required after the install of the new application?
--Yes , If you are installing NTP ( Network Threar Protection) it requires a reboot to get activated
