You can migrate a Web server from supporting an earlier version of WebSphere Application Server to support the current version.
The plug-in configuration file (plugin-cfg.xml) generated after successful migration from Version 5.x to Version 6.0.x is topology centric—that is, it includes all the applications within a cell. You cannot manage this cell-wide plug-in configuration file from the Version 6.0.x administrative console. It can be managed using the GenPluginCfg command or by using the Plug-in Config Generator MBean.
Be aware that regenerating the plug-in configuration can overwrite manual configuration changes that you might want to preserve.
The application-centric generation of the plugin-cfg.xml file is supported using the Version 6.x administrative console. Being application centric means that the plugin-cfg.xml file generated in the administration console has a granularity that allows each application to be mapped to its specific Web or application server.
