  1. Introduction to Exchange Online Migration

  2. Exchange Online Migration? This approach allows you to move existing mailboxes instead of creating new user mailboxes and importing user information. This approach is different than Exchange Mailbox Migration of users from an on-premises Exchange organization to Exchange Online as part of a complete Exchange migration to the cloud

  3. Office 365 Migration Checklist involves • Communicate the transition – The internal and external stakeholders need to be prepared in advance before starting out the exchange migration. Communicate the migration plan, time frame, and the day of the cutover migration. • Prepare details of migration – This includes the preparation of on-premises exchange inventory. The number of mailboxes, storage locations, DNS, etc. • Current infrastructure assessment  • Ensure the data to be migrated is ready

  4. Different methods for migration Cutover Migration method: Cutover migration is the most common method for migrating data from on-premises systems to the cloud. It involves taking a complete copy of a system’s data, cutting over the old system’s functions to the new system, and then bringing the old system back online. Staged Migration: A staged migration is suitable for mid-sized companies. This migration method is used to move users and mailboxes from on-premise Exchange 2003, 2007 to Exchange Online. This method migrates the Exchange to Office 365 over a period of time. Once it is complete, the mailboxes are then hosted on Office 365.

  5. IMAP Migration: This migration method is used when a non-Exchange mail system is involved. IMAP migrations are capable of moving e-mail messages only however, contacts, calendars, and tasks are lost during the process. This method is sometimes used as a shortcut to move from the older versions of Exchange Server (Exchange 2000 & newer supported) to the cloud. • Hybrid Migration: Exchange hybrid migration is the most flexible method and also complicated one. This method is most used by large organizations. Under this method, the Exchange admin creates a hybrid Exchange Server deployment by constructing a coexistence between the local Exchange Server and Office 365. 

  6. Migration and its Types There are 3 types of Microsoft Exchange to Office 365 migration: • Minimal Hybrid Migration: This is suitable for small and mid-sized businesses. Under this type, contents of user mailboxes are  migrated to Office 365 in a course of a couple of weeks or less. It is also known as Express Migration.  There are several pre-requisites to be followed when performing the Express migration. • Full Hybrid Migration: Unlike Minimal Hybrid Migration, Full Hybrid is a longer-term migration that includes support for extra  features, archiving, e-discovery, free/busy scheduling, multimedia, and also SharePoint integrations. • No-Hybrid Migration: This type of hybrid migration is used, when a non-exchange to Office 365 is performed. It is typically  used when there’s no compatibility between the existing environment and Office 365. In this case,  manual import and export processes are carried out
