Your first step before beginning a migration should be to ensure that the environment is reasonably error free and correct any underlying issues prior to migration.

 Patching your Exchange Environment

  • Hybrid migration or tool-based migration?
  • If you are thinking about moving your Exchange environment to Office 365 then you’re probably aware there are many options available.
  • From Microsoft, you have options for a Staged Migration and a Cutover Migration as well as a Hybrid Migration, and from third-party vendors a large number of different tools on the market for email archive migrations.
  • In general, if you have a version of Exchange Server that’s supported by Microsoft (Exchange Server 2010 and above) and it is part of your Active Directory then your default option should be an Exchange Hybrid Migration.
  • An Exchange Hybrid is based on either minimal or full Exchange Hybrid and creates a relationship between your on-premises Exchange servers and Exchange Online. This allows native mailbox moves, similar to between on-premises Exchange servers, with Outlook clients natively switching over without even needing to re-download offline copies of email. With full Hybrid, this also extends to secure mail flow between the two environments and co-existence functionality like free/busy and calendar sharing.

Azure AD

  • Azure AD Connect complements Exchange Hybrid, and you should expect to use Hybrid if you plan to synchronize your identity to the cloud. Azure AD Connect synchronizes your local Active Directory domain to Office 365, creating a copy of local AD accounts in Azure Active Directory that link back to the master copies. Azure AD Connect is also the part of the puzzle that maintains a consistent Global Address List between on-premises and the cloud.
  • Because AD and Azure AD Connect understand when there’s an existing Exchange organization in place, existing mailboxes on-premises won’t have mailboxes created in Office 365. You’ll be expected to use Exchange Hybrid to move mailboxes.
  • With a tool-based migration, the same rules do not apply. A fully Microsoft-supported Exchange Hybrid migration provides an excellent experience. However, especially in multi-forest environments it can be complex to set up correctly, hosted environments often do not allow for Azure AD Connect or Exchange Hybrid to be configured; and if you have legacy versions of Exchange it can involve installing additional servers running Exchange 2010 or higher which include the Hybrid components. Therefore, there are valid uses for a bespoke tool to migrate email to Office 365 – but in this article, we’ll assume you’ve made the decision to use Exchange Hybrid.

Methods for migrating to Office 365

  1. Understanding pre-requisites and dependencies
  2. Once you’ve decided that migrating to Office 365 using Exchange Hybrid is suitable for your organization, and you have a healthy environment to migrate, then you need to ensure you’ve completed necessary planning activities.
  3. Many organizations who begin this journey will at this point ensure they have a design in place to support the changes that will take place. However, as you aren’t designing Office 365 or Exchange Online and instead designing the bridge to Office 365 then the design is often not as detailed as a full Exchange migration.
  4. Instead, you are focusing on the changes necessary to your existing environment to make sure it is ready for the changes. In this article, we won’t cover this, but it’s worth remembering that most organizations, large and small, don’t just head into the unknown without making plans first.
  5. The key pre-requisite for migrating to Exchange is ensuring the correct identity model is in place, first. There is a variety of options available when choosing an identity, but the most common scenario will be to utilize Azure AD Connect with synchronized identities and password hash sync.

This may help you,
