Tendances des migrations Serveurs/Données

Why do your customers migrate?

72%

of organizations migrate on weekends which

adds to the labor costs associated with a migration

46%

• Serveurs/Stockages anciens ou plus

maintenus

• Applications plus supportées

• Amélioration des performances

• Consolidation Infrastructure

• Adoption de la virtualisation

• Réduction des coûts

(12)

Quels sont les challenges lors d’une migration ?

• Inventaire & préparation (groupes de consistance…)

• Temps d’arrêt de production conséquents

lors de la migration d’applications

• Planification hors heures ouvrées (Weekend, pont et nuit)

• Compatibilité lors des changements de plateformes Hardware - hyperviseurs

• Problèmes non identifiés post migration

• Pénalités en cas de retard

• Méthode de synchronisation & restauration incompatible avec les SLA exprimés

• Politique de sécurité interne à l’entreprise

• Manque d’éxpérience des équipes concernées

• D’autres projets à gérer simultanément

• Test des environnements migrés
