This section describes how to upgrade Exchange 2007 to Exchange 2007 SP3, using the Exchange 2007 Upgrade Wizard. It is applicable only if you already have Exchange 2007 set up in an InfoScale environment.

Note:

The procedure given below describes how to upgrade Exchange 2007 to Exchange 2007 SP1. This procedure can also be used to upgrade Exchange 2007 SP1 or SP2 to Exchange 2007 SP3.

Before upgrading the Exchange Server service pack

Before you proceed to upgrade the Exchange Server service pack, note the following:

Ensure that the Exchange 2007 service group is offline in the cluster.
While performing the upgrade the Exchange 2007 Upgrade Wizard renames and then restarts the cluster node. Exit all the other programs before you run the wizard on a cluster node.
Ensure that the Exchange database and registry replication files are configured on separate volumes. Configuring the Exchange database and the registry replication files on the same volume may cause data corruption, after you upgrade Exchange with the latest service pack.

If you fail to configure the Exchange database and the registry replication files on separate volumes, and the data gets corrupt after upgrading Exchange with the latest service pack, perform the following steps as a workaround:
- Delete or rename the file that could not be restored. Refer to the agent logs for the list of files that could not be restored.
- Bring the Regrep resource online.

Complete the following steps on all cluster nodes that are part of the Exchange 2007 service group, one node at a time.

To upgrade Exchange 2007 to Exchange 2007 SP3

Launch the Exchange 2007 Upgrade wizard on one of the cluster nodes from Start > All Programs > Veritas > Veritas Cluster Server > Configuration Tools > Exchange 2007 Upgrade Wizard or, on Windows 2012 operating systems, from the Apps menu in the Start screen.
Review the information on the Welcome panel and click Next.
On the Exchange Virtual Server Selection panel, select the Exchange virtual server that you want to upgrade and then click Next.
The Summary table provides the details of the Exchange virtual servers in the cluster and their upgrade status on each cluster node.
The wizard performs the tasks required to set up the VCS environment for the Exchange upgrade. The Tasks table displays the progress of the various tasks. After all the tasks are completed, click Next.
Review the information on the Cluster Node Reboot panel and then click Reboot. The wizard prompts you to reboot the node. Click Yes to reboot the node.
The Exchange virtual server name is temporarily assigned to the cluster node. On rebooting the node, the Exchange 2007 Upgrade Wizard is launched automatically with a message that the Exchange pre-upgrade tasks are complete. Do not click Continue at this time. Wait until after the Exchange upgrade is complete.

Run the Exchange 2007 SP1 installer to upgrade Exchange 2007 on the node. Type the following at the command prompt:

<drive letter>:\setup.com /mode:Upgrade

Here <drive letter> is the drive where the Exchange SP1 installer is located.

Note:

You can also run Setup.exe to launch the installer GUI for upgrading Exchange. If using the installer GUI, ensure that you do not select any other Exchange 2007 server role. Only the Mailbox server role must be upgraded.

Verify that the upgrade has completed successfully. In case there are errors or if the upgrade has partially succeeded or has failed, resolve the errors and ensure that the upgrade is successful.

Refer to the Microsoft Exchange documentation for more information.

Return to the Exchange 2007 Upgrade Wizard and click Continue.
If the wizard is not running, start the wizard from Start > All Programs > Veritas > Veritas Cluster Server > Configuration Tools > Exchange 2007 Upgrade Wizard or, on Windows 2012 operating systems, from the Apps menu in the Start screen.
The wizard performs the tasks required to set up the VCS environment after the Exchange upgrade. The Tasks table displays the progress of the various tasks. After all the tasks are completed, click Next.
Review the information on the completion panel and then click Finish.
The wizard displays the status of the Exchange virtual server upgrade. The Summary table provides the details of the Exchange virtual servers in the cluster and their upgrade status on each cluster node.
Repeat these steps on the remaining cluster nodes. After you have upgraded all the cluster nodes that are configured to host the Exchange virtual server, bring the Exchange 2007 service group online in the cluster.

Note:

Do not bring the Exchange 2007 service group online until you have completed the upgrade on all the cluster nodes that are part of the service group.
For a disaster recovery environment, repeat this procedure at the secondary (DR) site.
