Upgrade from 1.6.0 to 1.6.2 from source

Im having an issue related to my FXO trunks apparently related to the version of asterisk we are running. I have been told the issue was resolved in 1.6.2 so I need to upgrade. I compiled everything I currently have running from source. I have the new source for 1.6.2, what would be the procedure for the upgrade?
