Sun Java System Web Server 7.0 enables you to migrate server instances from Web Server 6.0 and 6.1 to Web Server 7.0. For a general overview of this terminology and distinction, see New Administration Framework.
You must first migrate the Web Server 6.0 and 6.1 instance to create a Web Server 7.0 configuration. The Web Server 7.0 configuration is then used to create a Web Server 7.0 instance. Web Server 7.0 includes a new command-line interface for migration, so migration can now be performed either from the graphical interface or from the command line. See Migrating Using the Graphical Interface or Migrating Using the Command-Line Interface for specific procedures.
The server being migrated and the Web Server 7.0 Administration Server must reside on the same host. However, an instance can be created on an associated remote node.
Only Web Server 6.0 and 6.1 instances can be migrated. Direct migration from a Web Server version lower than 6.0 is not supported. Older versions such as iPlanetTM Web Server 4.0 and Sun ONE Web Server 4.1 must first be migrated to Web Server 6.1, then to Web Server 7.0. After migrating from iPlanet Web Server 4.0 and Sun ONE Web Server 4.1, ensure that Web Server 6.1 works fine, then migrate to Web Server 7.0. For information about migrating from iPlanet Web Server 4.0 and Sun ONE Web Server 4.1, see the latest Sun Java System Web Server 6.1 Installation and Migration Guide and Release Notes at http://docs.sun.com/app/docs/coll/S1_websvr61_en.
Detailed migration information is provided during and after the migration process in the migration log file. It lists the settings and configurations that were and were not migrated, warns about required manual changes, and indicates whether the migration succeeded or failed. For more information about this file, see Viewing the Migration Log File. Many but not all settings are migrated, as described in What Is and Is Not Migrated.
A configuration is created during the migration process. Following migration, the configuration is available in the install_dir/admin-server/config-store directory. As mentioned earlier, Web Server 7.0 server instances are created from these configurations using either the administration GUI or CLI. If a configuration exists with the same name, -x is added to config_name, where x is an integer.
