You will need upgrade ESXi license only if you are upgrading major release, i.e. 5.X to 6.X, if you upgrade from 5.0 to 5.0U1 or 5.5 you do not need new ESXi license.  As to the upgrade itself it's very easy and you can google for how ti upgrade ESXi with many great youtube videos and official vmware guides.
