Manual Methods to Migrate Exchange 2013 into Microsoft Office 365

Exchange Cutover Migration – This method carries out the migration of all mailboxes in one go. As all the On-Premise mailboxes are transferred simultaneously, it makes it difficult for the users to process a large number of mailboxes. This approach supports up to 2000 mailboxes but is best suited for 150 or fewer mailboxes and can be used for Exchange 2016, 2013, 2010, 2007.

Exchange Staged Migration – This approach is useful when the organization wants to transfer many Exchange mailboxes. But it has a limitation associated with it i.e. it only supports Exchange 2003 and 2007. Therefore, if an organization is using any of these versions, then they can choose staged migration.

Hybrid Exchange Migration – The hybrid migration process is best suitable if there are many Exchange mailboxes to be migrated. This method helps an organization to maintain both online and On-Premise mailboxes and progressively migrate data into Microsoft Office 365 cloud. Although this process is smooth, but it is complex and time taking as it is carried out in small batches.

If in case a user skips a step during the migration, the process remains incomplete. This method can be used to migrate Exchange 2013 to Office 365 as well as Exchange 2010 mailboxes.

IMAP Based Migration – This is a slow and long process. In the IMAP email migration process, you first have to create user accounts on Office 365 cloud and then start migrating email messages. This takes a lot of time and effort and only exports emails to the destination account.

Shortcomings of Manual Methods

The manual procedures are time taking and can be complex for users who are new to either Microsoft Exchange or Office 365. Moreover, these methods do not guarantee that users will get 100% data after the conversion process. Thus, the users who don’t want to lose their crucial data while migrating Exchange 2013 On-Premise into O365 cloud are recommended to use the third-party application mentioned above.

It will help users to carry out the complete process in a hassle-free way without any data loss.


Enterprise asset management is complex and time-consuming. Whether under or over-maintenance, both create complexity, from the IT staff to the end-users. Failure to maintain leads to loss of productivity, which creates avoidable security gaps and usually leads to higher costs. Excessive maintenance leads to avoidable downtime and higher costs. It’s always better to switch your paradigm to more useful, less distracting, and cost-effective Microsoft Office 365 and to migrate Exchange 2013 to Office 365.
