If I plan to install a newer version Ubuntu,
- how shall I know what software that
were installed on my previous
Ubuntu, if I want to reinstall them?
Is there a convenient way to install
all previous softwares? - How can I keep the settings and
configurations for the software? - will it be possible for the newer
version Ubuntu, the software
installed for the older one cannot
be found for the newer one? - will there be other considerations
regarding installation of previous
software?
Thanks and regards!

On #1, to get a list:
To reinstall the list on a new installation:
On #2, you need to know where configuration files are located. (Backup the files in /etc and your home directory at least).
On #3, yes it is possible. Yet, later you could find out how to install a missing application, though another repository, possibly.
