Upgrade Tool: An Overview

Use the Upgrade Tool to transfer configuration information from an Application Server 9.1 or GlassFish Prelude installation to a GlassFish Server Open Source Edition 3.1.1 installation. Information that is transferred includes data about deployed applications, the file realm, security certificates, and other resource and server configuration settings.

The tool automatically detects the version of the specified source server installation.

Note: Before starting the upgrade process, make sure that both the source server (the server from which you are upgrading) and the target server (the server to which you are upgrading) are stopped.
