SharePoint 2007: The Definitive Guide

Possible Upgrade Options

In an in-place upgrade, you will be installing Office SharePoint Server 2007 on your existing environment. The previous version is overwritten with the new version, and the content databases are changed. Hence, this is not a reversible process—you cannot roll back to the previous version. When you run the in-place upgrade, the process upgrades your entire installation in a preset sequence. The following list shows the steps that need to be taken to implement an in-place upgrade. (For this in-place upgrade, I have an existing SharePoint Portal Server 2003 environment set up. It is a basic out-of-the-box setup with a couple of Windows SharePoint Services v2 sites and no customizations.)
