Clients- Outlook 2013, Outlook 2010, Outlook 2007 + updates - Outlook Web App (in Exchange Online)

Exchange Server- E2013 users can access E2013 / E2010 / E2007 Public Folders- E2007/E2010 users cannot access E2013 Public Folders, so migrate Public Folder users before Public Folder data

Migration support- Cutover migration from E2010 and E2007- Same forest and cross-premise

Public folder architecturePublic Folder databases replaced by mailboxes

High availability, data redundancy, and low cost storage support through use of DAGs

Multi-master replication simplified and replaced by single-master replication of folder hierarchy

Public Folder architecture

Architectural bet Public folders are based on the mailbox architecture

Details• Hierarchy is stored in all public folder mailboxes• Content can be broken up and placed across multiple mailboxes• Similar administrative features• No end-user changes

How to Migrate?Like one big online mailbox move, but migrate users

first.

• Make sure source is running Exchange 2010 SP3 or 2007 RU10

• Make sure replication between source public folder databases is healthy

• Migrate users to Exchange Server 2013 or Exchange Online

• All Public Folders are cut over to E2013 together There will be a short downtime while the migration is finalized Once migration completes, everyone switches at the same

time Admin can choose to switch some users on first for validation

Before beginning to migrate…
