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.

  • Calendars and delegates features are not available during the migration

2. Cutover Migration

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

3. Hybrid Migration
