After saving your configurations in /etc, even better would be something like this

on the old system
  aptitude -F '%p' search '~i!~M' > manually-installed

take the file "manually-installed" to the system to be installed and command, e.g.,
  xargs < manually-installed aptitude -y install


Alternatively, save at least the information which packages are installed
automatically and restore that information:

on the old system
  aptitude -F '%p' search '~M' > automatically-installed

take the file "automatically-installed" to the otherwise restored system and
command, e.g.,
  xargs < automatically-installed aptitude -y markauto
