La fin du support officiel pour Microsoft Exchange Server 2016 et 2019 est fix\u00e9e au 14 octobre 2025, ce qui signifie l’arr\u00eat complet des mises \u00e0 jour de s\u00e9curit\u00e9, des correctifs critiques et de l’assistance technique. Continuer \u00e0 utiliser ces versions apr\u00e8s cette date expose fortement votre infrastructure \u00e0 des cyberattaques, des vuln\u00e9rabilit\u00e9s non corrig\u00e9es et des probl\u00e8mes de conformit\u00e9, notamment avec des r\u00e9glementations comme le RGPD. Dans un environnement critique, cette vuln\u00e9rabilit\u00e9 est particuli\u00e8rement pr\u00e9occupante, car elle peut compromettre la continuit\u00e9 de vos activit\u00e9s et la s\u00e9curit\u00e9 de vos donn\u00e9es.<\/p>\n\n\n\n

Pour bien pr\u00e9parer votre migration, une planification d\u00e9taill\u00e9e est essentielle. Commencez par faire un inventaire pr\u00e9cis de vos versions d’Outlook, de vos serveurs Exchange et de toutes vos configurations existantes. \u00c9valuez vos besoins sp\u00e9cifiques : si la s\u00e9curit\u00e9 renforc\u00e9e, la maintenance simplifi\u00e9e et l’acc\u00e8s \u00e0 des fonctionnalit\u00e9s collaboratives modernes sont prioritaires, la migration vers Exchange Online dans Microsoft 365 est g\u00e9n\u00e9ralement la solution id\u00e9ale. Cette option offre une protection automatis\u00e9e contre les nouvelles menaces, une sauvegarde automatis\u00e9e et une gestion centralis\u00e9e simplifi\u00e9e. Si la gestion locale des donn\u00e9es est imp\u00e9rative pour des raisons de confidentialit\u00e9 ou de r\u00e9glementation, la migration vers l’Exchange Server Subscription Edition (SE), pr\u00e9vue pour la seconde moiti\u00e9 de 2025, constitue une alternative.<\/p>\n\n\n\n

La migration d’Exchange 2016 vers 2019 est possible, mais elle doit \u00eatre suivie d’une mise \u00e0 niveau vers l’Exchange Server SE pour rester \u00e0 jour. Pour une migration vers Exchange Online, il est crucial de dimensionner les lots de migration en fonction de la capacit\u00e9 maximale, de la bande passante disponible, de la criticit\u00e9 de l’environnement et de la disponibilit\u00e9 d’une \u00e9quipe support locale. Une migration r\u00e9ussie n\u00e9cessite \u00e9galement un test pilote sur un petit groupe d’utilisateurs pour identifier et r\u00e9soudre les probl\u00e8mes avant le d\u00e9ploiement g\u00e9n\u00e9ral. La formation des utilisateurs aux nouvelles interfaces est \u00e9galement un point cl\u00e9 pour \u00e9viter une perte de productivit\u00e9.<\/p>\n\n\n\n

En choisissant d’accompagner votre migration avec un partenaire comme INGEFLEX, vous b\u00e9n\u00e9ficiez d’une expertise pour anticiper les budgets de licences, planifier les changements et assurer une transition sereine. Leur accompagnement est particuli\u00e8rement pertinent pour les environnements critiques, car il permet de transformer cette transition obligatoire en une opportunit\u00e9 strat\u00e9gique pour renforcer la posture de cybers\u00e9curit\u00e9 et la p\u00e9rennit\u00e9 de votre infrastructure. Agir d\u00e8s maintenant est crucial, car chaque jour pass\u00e9 augmente votre vuln\u00e9rabilit\u00e9 face aux menaces.<\/p>\n\n\n\n
