exchange migration

Deciding on the best migration path of your users’ email to Office 365 can be difficult. As part of our migration process we will be performing an assessment your current current email system. The version of your existing Exchange Server platform will have a significant factor into deciding on what migration method to use. Also, your migration performance will vary based on your network, mailbox size, migration speed, and so on. Not to worry, DMS will guide you through the discovery process and will plan the migration based on on any technical limitations, best practices and ultimately your requirements.

As part of an Office 365 deployment, you can migrate the contents of user mailboxes from a source email system to Office 365. When you do this all at one time, it’s called a cutover migration. Choosing a cutover migration is suggested when:

  • Your current on-premises Exchange organization is Microsoft Exchange Server 2003, Microsoft Exchange Server 2007, Microsoft Exchange Server 2010, Microsoft Exchange Server 2013, or Exchange Server 2016.
  • Your on-premises Exchange organization has fewer than 2,000 mailboxes.

As part of an Office 365 deployment, you can migrate the contents of user mailboxes from a source email system to Office 365. When you do this over time, it’s called a staged migration. A staged migration is recommended when:

  • Your source email system is Microsoft Exchange Server 2003 or Microsoft Exchange Server 2007.
  • You have more than 2,000 mailboxes.

A hybrid deployment offers organizations the ability to extend the feature-rich experience and administrative control they have with their existing on-premises Microsoft Exchange organization to the cloud. A hybrid deployment provides the seamless look and feel of a single Exchange organization between an on-premises Exchange organization and Exchange Online in Microsoft Office 365. In addition, a hybrid deployment can serve as an intermediate step to moving completely to an Exchange Online organization.
