Upgrading from point release is very easy. However, if you are skipping one or two releases and upgrading to Ubuntu 14.04 it may not be very straight forward if you go the traditional way.
But, a simple 5 step command line approach can help you overcome that problem. Below are the steps to upgrade from Ubuntu 13.04 (Raring Ringtail) to Ubuntu 14.04(Trusty Tahr).
Before you start, please remember back up all your documents and all other data that you consider important.
