About the Upgrade Process

To upgrade GlassFish ESB, you need to install an instance of GlassFish ESB v2.2 in a separate directory from your existing GlassFish ESB environment, and then migrate the runtime components from the old GlassFish ESB environment to the new v2.1 environment. GlassFish provides a tool, asupgrade, to help you migrate the runtime components.

Upgrading to GlassFish ESB v2.2 requires two installers – the full installer and the component installer. The full installer installs a complete GlassFish ESB v2.2 environment. However, when you use the GlassFish upgrade tool to migrate the runtime configuration settings and applications, the default 2.2 domain is deleted and the tool migrates the existing domain into the 2.2 environment. In this new domain, the runtime components are still at the previous version of GlassFish ESB. Running the component installer for the runtime components upgrades the components to v2.2.
