Use the Readiness Checks page to view the prerequisite checks for the Exchange server roles that will be upgraded by the Exchange Server 2007 SP1 Setup wizard. 

The Readiness Checks page displays a progress bar and the elapsed time for each of the prerequisite checks. If the wizard finds any errors, you will not be able to upgrade to Exchange 2007 Service Pack 1 (SP1). If the wizard returns any warnings, you will still be able to upgrade to Exchange 2007 SP1.

Click the arrows to show or hide detailed information about each of the prerequisite checks.

You can press CTRL+C to copy the text in the summary pane to the Clipboard. After the text has been copied to the Clipboard, you can paste it into a document or screen.

Click Upgrade to begin the upgrade.

After you click Upgrade, you cannot cancel the upgrade.

If any of the prerequisite checks fails, click Retry after you have resolved the problem to perform the readiness checks again.

The wizard uses the engine from the Microsoft Exchange Server Best Practices Analyzer Tool to check the prerequisites. This engine gathers information about your server and your organization, and then evaluates that information against a set of rules. The rules are stored in the ExBPA.PreReqs.xml file, which is located in the Setup\ServerRoles\Common\<language> directory. If the server can access the Internet, Setup checks for a more recent version of the prerequisites file than the one that is located in the Setup\ServerRoles\Common\<language> directory. If the server cannot access the Internet, or if there is not a more recent file available, Setup uses the local prerequisites file.
