In the third part of a six-part email migration from on-premises Exchange server to Exchange Online series, we will be discussing about choosing the perfect migration method for your organization. As a migration administrator, you must decide the right type of migration method based on the available resources to get optimal results.

Note: Refer to the best practices to be followed before migrating and permissions required to perform migration.

To migrate all mail data, contacts, calendar items, and tasks from on-premises mailboxes to Microsoft 365 you have three widely used methods:

  1. Cutover migration.
  2. Staged migration.
  3. Minimal hybrid migration.

Choosing the proper migration methods depends mainly on three factors:

  1. Exchange Server version.
  2. Number of mailboxes.
  3. Migration time span.
