Migrating to office 365

This document discusses migrating to Office 365. It covers co-existence options like shared or multiple address spaces when also keeping an on-premise Exchange server. Types of migrations include IMAP cutover, Exchange cutover, staged coexistence, and hybrid coexistence. Setting up single sign-on requires Active Directory Federation Services and DirSync. A real-world migration example outlines planning, choosing a migration type, and using the Exchange Control Panel to complete a 400 user migration over 5 days.

- 4. Co-Existence • You already have onPremise Exchange • Shared Address Space – Use the same domain name for all users – OnPremise or cloud receives email – Forwards onto the other one • Multiple Addresses – Use different domain names for onPremise & Cloud – Each entity receives its own email – Manage mail contacts in either onPremise or cloud 023 8097 0968 www.spedutech.com
- 5. Types Of Migration • IMAP cutover: E-mail is extracted from the source mail system by IMAP, DNS MX records are changed, and workstations configured to connect to Office 365. E-mail is moved, but no contacts and calendars. • Exchange cutover: Same as IMAP but it uses RPC over HTTPS (Outlook Anywhere) to extract your entire mailbox from a legacy Exchange e-mail system (2003 or later only). • Staged coexistence: Similar to an Exchange cutover, but allows for batches of users to move at a time and for the two systems (Exchange and Office 365) to interoperate over a period of time. • Hybrid coexistence: This solution is intended for customers who require onsite and cloud e-mail systems to coexist for longer periods. Active Directory and Office 365 synchronize and single-sign-on is set up. This is the most technically complex migration method but makes for the easiest mailbox migrations, simply using the existing Exchange Management Console’s commands. 023 8097 0968 www.spedutech.com
