1. Staged Migration

It allows the movement of data in batches. It covers mailboxes & existing users to Exchange Online from Exchange 2003 or 2007. This type is ideal for a medium-sized organization having more than 2000 mailboxes.

  • Emails can be sent and received during the migration (only for users, whose migration is not done)
  • Calendars and delegates features are not available during the migration

2. Cutover Migration

This Office 365 Migration Type involves an immediate transition to Office 365. In this, the contacts, mailboxes, and other resources are migrated in one instance. The selection of specific parameters for migration is not available.

  • Ideal for less than 2000 mailboxes.
  • Every user profile will require reconfiguration for connecting to Office 365

3. Hybrid Migration

The Office 365 hybrid migration involves integrating Office 365 with the on-premises Exchange Servers PLUS your existing directory services. In both environments, user accounts can be managed and synchronized.
