Overview of Upgrading from a Previous Version
CentraSite is installed using the Software AG Installer. Beginning with version 9.7, CentraSite does not support overinstallation. Instead, if you are upgrading to CentraSite 9.7 from an earlier version of CentraSite, you must use the side-by-side (SBS) installation procedure. For detailed upgrade instructions, see Upgrading webMethods and Intelligent Business Operations Products .
Before upgrading, Software AG recommends that you read the CentraSite readme document, which is available on the Software AG Documentation website.
