EASY or not to ? UPGRADE LION 10.7.5 to MOUNTAIN LION 1.8.x

voila je voudrais faire la mise a jour de mon HP4530s Lion 10.7.5 vers la version MLion 10.8.x.
Est ce que je dois tout recommencer ? ou c'est à dire une réinstallation totale ?

Ou dois je appliquer la version 10.8.x Retail Install et apres appliquer le HP INSTALLER beta12 en cochant les bons choix ( 10.8.x ) et redemarrer ?

Merci de votre aide et informations

I want to make here is the update of my HP4530s Lion 10.7.5 to version 10.8.x. MLion
Is what I have to start all over again? or ie total reinstallation?

Or should I use the version 10.8.x Install Retail and after applying the HP INSTALL beta12 by checking the choices (10.8.x) and reboot?

Thank you for your help and information

I have never tried an "upgrade" install like you propose. Clean installs are preferred. Either way, you create a Unibeast flash and install by booting it via F9. Difference is whether you erase the target partition in Disk Utility first or not...
