Vous pouvez utiliser les méthodes Modifier la base de données Modifier le fichier ou Détacher / Attacher.
Remarque: les deux nécessiteront un certain temps d'arrêt, donc doit être fait pendant la fenêtre de maintenance.
Cela suppose que vous avez la même structure de répertoires sur le nouveau lecteur, par exemple C: \ data \ et D: \ Data.
