Exchange Server 2013 to Office 365 using hybrid migration:

Hybrid migration maintains both online premises and online mailboxes. In this method, there is no need to create a new mailbox and import information. The users can transfer the existing mailbox between the exchange server and exchange online. It is considered a smooth process, but if the user skips any of the steps, it fails. The approach mentioned above is very time-consuming.

Before performing the Migration, you need to ensure your Exchange server 2013 is updated with the latest patch. You also need to set up directory synchronization using Azure Active directory connect.

  • Verify the domain click on > Setup & Domain > Add Domain
  • Click Setup & Data Migrationselect data service > Click on the Exchange.
  • Accept default values fill Exchange and office 365 credentials.
  • Select minimal hybrid configuration and click Next.
  • Click on the Update to prepare your Exchange to O365 Migration.
  • Synchronize local users to Office 365 using Azure AD Connect.
  • Assign the licenses by clicking users and active users.
  • Click on Setup > Data Migration > click on Exchange.
  • A Migration process will start automatically.

Staged migration

Another manual method, Staged migration, allows the migration of numerous mailboxes, i.e., greater than 2000. It maintains both online premises and online mailboxes. It is one of the most suited options for both medium and large-size organizations. A Staged migration only works with exchange 2003 and exchange 2007. If you have an Exchange Server 2003 or 2007, then Staged migration is the optimum solution. The Staged migration takes several days to complete the task. It depends upon the volume of content and the mailbox number.

IMAP migration

Internet Message Access Protocol (IMAP) fails to migrate anything other than email and message. IMAP migration is a long and slow process compared to other methods mentioned in this article. It can only migrate emails that are up to 35 MB in size and 500,000 items per mailbox. The IMAP method is preferable to migrate from the non-exchange server platform to Office 365. The only drawback of this method is, it can only migrate inbox items or email folders. It fails to migrate contacts, calendars, etc.

Why Professionals Avoid Manual Exchange to O365 Migration:

Manual migrations have some limitations. This article outlines some common issues with manual Migration to office 365 from the Exchange server.

Migration of many mailboxes to Office 365 may take a long time because you have to migrate the mailboxes in stages and over a while. For example, if you need to migrate 5,000 mailboxes, you will have to migrate 300 per day until you have completed the Migration. Exchange Online has a retention policy named “Default MRM Policy” to resettle items in the user’s mailbox. This retention policy is created when Exchange Online is enabled for your organization. Items older than 30 days are moved to the user’s archive mailbox employing MRS Proxy. Items older than 25 days are transferred to the user’s archive mailbox through MRS Web Access.

  1. In the cut-over Migration, the maximum limit to migrate is 2000 mailboxes. However, the recommended limit is only 150 mailboxes.
  2. Some emails might be lost until the DNS record is entirely changed.
  3. Hybrid mailbox migration consists of complex steps and additional administrative efforts.
  4. As a part of the migration method, Staged Migration can be considered a slow process as it needs to be done in stages. The initial Migration of mailboxes from the On-Premises Exchange Server is not processed immediately. Because Office 365 will first process the data being migrated and then forward it to the On-Premises server for the following processing stage.
  5. IMAP Migration is only effective for mailbox not suitable for attachments and other mailbox items.
