cette dernière ligne étant on-ne-peut-plus claire.
Je pense connaitre la réponse à ma question... Existe-t-il un moyen de passer de 32 bit à 64 bit sans tous réinstaller ?
En utilisant une méthode du type preupgrade ou yum ?
Ou suis-je condamné à faire une installation toute fraiche, puis à copier mes données ainsi que mes programmes persos ?
