In Part 2 we demonstrate the quick upgrade scenario – following our usual Step-by-Step approach. Our main goal is to provide detailed, from start to finish instructions about the upgrade process from Exchange 2003 to Exchange 2010 SP1.
To keep the logical flow of the upgrade uninterrupted, we have included the installation of a GoDaddy Multiple Domain SSL certificate/UCC, instead of publishing a separate Screencast about it. The correct installation and configuration of Multiple Domain certificate in Exchange 2010 SP1 is crucial to completing the upgrade with minimal interruption to the end users, so we focus a lot of our attention on it – Step3 and Step4.
Moving the mailboxes is probably one of the most hectic moments. We demonstrate how to perform and monitor the move both in Exchange Management Console and Exchange Management Shell (especially useful if you have to bulk move a large number of mailboxes). Once the process completes, we test the result using local clients (both cases – when the client is up and running and when the client is closed) and remote clients (OWA, Outlook Anywhere and ActiveSync). Often, one of the overlooked tasks is Moving All Public Folder replicas.
If there are issues with Public Folder replication, this could bring your upgrade to a stall. As you will see, Exchange 2003 cannot be decommissioned until the list of Public Folder Replicas on the server is empty. Following the principle that it’s better to be prepared and expect problems than to be surprised, we show you how to configure and use diagnostic logging and message tracking on both exchange servers, and how to monitor the public folder replication. If you are pressed on time we discuss an option to speed up the replication process.
