This is the second (and last) part of our step-by-step video tutorial, which demonstrates how to upgrade Exchange 2007 to Exchange 2010 Sp2. In Part 1, we’ve been preparing the existing network and introducing Exchange 2010 SP2 into it.
In Part 2, we continue with moving all resources and decommissioning Exchange 2007 server. As usual, we follow our Step-by-step approach, where the whole upgrade is split into seven steps.
The first three steps prepare the ground for moving all resources to Exchange 2010:
Step 1 – Replicate Public Folders and move OAB generation server.
Step 2 – Generate and submit a CSR for a new SSL certificate to GoDaddy.com.
Step 3 – Install the new Certificate on Exchange 2010 and Exchange 2007 servers.
The mail flow and client connectivity should remain intact at this point. As you will see in the next two steps – good preparation and timing is crucial for minimizing downtime when changing the mail flow and remote client connectivity:
Step 4 – Change the mailflow through Exchange 2010 server.
Step 5 – Change remote client access – OWA, Outlook Anywhere and ActiveSync.
Moving the mailboxes to Exchange 2010 server can take a significant amount of time. You should be prepared for different scenarios, including troubleshooting failed move requests and automatically suspending moves to minimize the impact on the end users:
Step 6 – Move the mailboxes – troubleshoot failed move requests, automatically suspend moves and complete them after hours.
And the last step is moving all Public Folder replicas to Exchange 2010 and uninstalling the legacy server:
Step 7 – Remove Exchange 2007 Mailbox and Public folder DB and uninstall Exchange 2007 server.
