Yes. In your old installation, just click "File" > "Export setting" and chose a text file. In the new installation, select that file after clicking the "import" button on the blank session manager. (or, if you already created a session, than use File > Import settings)
To update that... Those things aren't in the session manager, and don't appear until you open a session. When the session with a specific database is open, you can then follow the steps (File >Export or File >Import) and it exports or imports the settings for all session names -- not just the one you are using.
