Changer d’h\u00e9bergeur inqui\u00e8te souvent : peur de la coupure, de la perte de donn\u00e9es ou d’un r\u00e9f\u00e9rencement d\u00e9grad\u00e9. Avec une m\u00e9thode rigoureuse, une migration WordPress se d\u00e9roule sans interruption perceptible pour vos visiteurs.<\/p>\n\n

\u00c9tape 1 \u2014 Pr\u00e9parer et sauvegarder<\/h2>\n

Avant toute chose, r\u00e9alisez une sauvegarde compl\u00e8te : fichiers (th\u00e8me, extensions, m\u00e9dias) et base de donn\u00e9es. Cette sauvegarde est votre filet de s\u00e9curit\u00e9. Notez \u00e9galement votre version de PHP et la liste de vos extensions pour reproduire l’environnement \u00e0 l’identique.<\/p>\n\n

\u00c9tape 2 \u2014 Recr\u00e9er l’environnement sur le nouvel h\u00e9bergement<\/h2>\n

Transf\u00e9rez les fichiers et importez la base de donn\u00e9es sur le nouveau serveur. Reconfigurez le fichier wp-config.php<\/code> avec les nouveaux identifiants de base de donn\u00e9es. \u00c0 ce stade, le site fonctionne sur la nouvelle infrastructure, mais votre nom de domaine pointe toujours vers l’ancien.<\/p>\n\n

\u00c9tape 3 \u2014 Tester avant de basculer<\/h2>\n

Testez le site sur la nouvelle infrastructure via une URL temporaire ou une modification locale du fichier hosts. V\u00e9rifiez l’affichage, les formulaires, le tunnel d’achat si c’est un e-commerce, et les liens internes. C’est le moment de corriger, pendant que l’ancien site reste en ligne.<\/p>\n\n

\u00c9tape 4 \u2014 Basculer le DNS proprement<\/h2>\n

La coupure redout\u00e9e vient presque toujours du DNS. Deux pr\u00e9cautions l’\u00e9vitent :<\/p>\n

    \n
  • R\u00e9duisez le TTL de vos enregistrements DNS 24 \u00e0 48 heures avant la bascule, pour que le changement se propage vite.<\/li>\n
  • Gelez le contenu pendant la fen\u00eatre de migration pour \u00e9viter qu’une commande ou un article n’arrive sur l’ancien site apr\u00e8s la copie.<\/li>\n<\/ul>\n

    Comme les deux serveurs affichent le m\u00eame site pendant la propagation, aucun visiteur ne voit de page d’erreur.<\/p>\n\n

    \u00c9tape 5 \u2014 Contr\u00f4ler apr\u00e8s migration<\/h2>\n

    Une fois le DNS propag\u00e9, v\u00e9rifiez le certificat HTTPS, les redirections, et surveillez les journaux d’erreurs les premiers jours. Conservez l’ancien h\u00e9bergement une \u00e0 deux semaines par prudence.<\/p>\n

    De nombreux h\u00e9bergeurs, dont OVHcloud, proposent des outils ou un accompagnement de migration qui automatisent une partie de ces \u00e9tapes, r\u00e9duisant encore le risque d’erreur manuelle.<\/p>","protected":false},"excerpt":{"rendered":"
