You need to pgdump your database cluster first before upgrading to a
major postgresql release, after that stop the postgresql server,
then rename (or delete, but this is not so good idea) the old
installation directory, and finally
lin postgresql. 
Here is a more detailed explanation:

Please, someone correct me if i'm wrong.
