 If you want you get a list of installed packages on a debian like system.
 use:

 dpkg --get-selections > packages.list

 Save the list somewhere, where it is safe.

 On the new system do the reverse.

 dpkg --set-selections < pakages.list

 apt-get upgrade

 should then install the packages that were aditionally installed on the
 previous system.

 If the apt-get upgrade does not install the packages from the list,
 google for examples with "dkpg --get-selections"
