Many companies want to give up their Exchange Server to convert it to Microsoft Office 365. Migration of an Exchange Server is often a complicated process, but it can minimize a certain strain by using an Exchange Server. Even after choosing a new destination, compliance must be checked, mailboxes and applications prepared, and new certificates and licenses planned. End-of-life in 2020, Exchange Server 2010 will be an active call for hosting a cloud service to organizations seeking centralized management, high availability, and scalability. To this end, companies can move Exchange Servers to Exchange Online, Office 365 or a hybrid deployment for more reasons.
Whether planning to relocate to a hybrid configuration or move to the cloud, first know the existing Exchange Server setup. Regulate the mail flow connector, learn e-mail gateway configuration and double check that all OSes and applications comply before launching. A switch is also the ideal time to review the services the company actually uses and cut costs. Upon understanding of recent settings, it is time for new destinations to be prepared. The organization will probably only need two Client Access Mailbox servers if everything–other than relays left on security premises–has been moved into Office 365 for a hybrid deployment. To import third-party certificates, use a service account, and then install Exchange. Create and deploy old server entries to relay email.
Whether moving to a new on-site server, hybrid environment or the cloud, the Exchange Server migration will first be studied. Exchange Online offers an attractive alternative to on-site servers, but it is a difficult task to move to the hosted message application. When Exchange Servers migrate away from the premises, mailbox performance slows down. That's why Microsoft recommends caching mailboxes. The cached mode makes any e-mails in secondary mailboxes unaccessible in Outlook prior to switching off Online mode.
Even though all seems to work, wait a couple of weeks before you shut down the old server to ensure it has been successfully sent all mailboxes, archives and public folders. If a requirement, update or connection is overlaid, the previous server can also provide a failback feature. The arbitration mailboxes can also be transferred to the new server database to decommission servers like Exchange 2013.
