Migrating from Exchange 2007 Unified Messaging (UM) to Exchange 2010 UM

DateFriday, January 22, 2010 at 03:50PM

Companies using Exchange 2007 UM who want to migrate to Exchange 2010 UM can gradually move users’ email boxes over a period of time, not in a flash cut, and still have voicemail services by following these steps:

 

  1. Stand up E2010 core
  2. Stand up E2010 UM
  3. Configure E2010 UM dial plans & policies
  4. Link the dial plans between the 2010 UM servers and 2007 UM servers
  5. Reconfigure VoIP gateways to point to 2010 UM servers
  •  If a UM 2010 server finds itself handling a call for a user whose mailbox is Exchange Server 2007, it will immediately try to hand off the call to a UM 2007 server in the same Dial Plan. Therefore, client must retain at least one UM 2007 server in any Dial Plan in which users have Exchange Server 2007 mailboxes.
  1. Reconfigure/test 2010’s native MWI
  2. Migrate all mailboxes to 2010
  3. Shut down 2007 UM and other roles
