Updating WebSphere eXtreme Scale on WebSphere Application Server

When you migrate WebSphere® Application Server to a new version, you can also migrate the WebSphere eXtreme Scale configuration to the new WebSphere Application Server installation.

Before you begin

  • It is assumed that both WebSphere eXtreme Scale Version 7 and WebSphere eXtreme Scale Version 8 are being installed on the same server.
  • Migrate WebSphere Application Server Version 7 to WebSphere Application Server Version 8. For more information, see Migrating product configurations.
  • Install WebSphere eXtreme Scale Version 8 on your WebSphere Application Server Version 8 installation. For more information, see Installing WebSphere eXtreme Scale or WebSphere eXtreme Scale Client with WebSphere Application Server. All WebSphere eXtreme Scale migration scripts must be run from WebSphere eXtreme Scale Version 8.5 or later. For example, if you are migrating from Version 7.x to Version 8, run the scripts for migration from the <WXS_v8_install_root>/bin directory.

About this task

When you install a new version of WebSphere Application Server that has WebSphere eXtreme Scale integration, you first upgrade WebSphere Application Server with the normal process. Then, install the new version of WebSphere eXtreme Scale on your new installation. Then, you can use the xsmigration script to move the WebSphere eXtreme Scale configuration information to the new WebSphere Application Server installation.

Procedure

  1. Migrate the deployment manager-related configuration from Version 7 to Version 8.
    1. Run the WebSphere Application Server backup script.
      For more information, see WASPreUpgrade command.
    2. Stop the deployment manager.
    3. Access the deployment manager server in your WebSphere eXtreme Scale configuration and run the migration script.
      1. Change the directory to: <WXS_v8_install_root>/bin
      2. Run the following command: 
        xsmigration.bat|sh -targetwashome <WAS8x_HOME> 
-sourcewashome <WAS7x_HOME> -targetprofilepath <WAS8x_DmgrProfile>
 -sourceprofilepath <WAS7x_DmgrProfile>
        where
        • <WAS8x_HOME> is the root location of the WebSphere Application Server Version 8.x installation. Example /opt/IBM/WebSphere8
        • <WAS7x_HOME> is the root location of the WebSphere Application Server Version 7.x installation Example:/opt/IBM/WebSphere7
        • <WAS8x_DmgrProfile> is the location of the WebSphere Application Server Version 8.x deployment manager profile. Example: /opt/IBM/WebSphere8/profiles/DMgr01
        • <WAS7x_DmgrProfile> is the location of the WebSphere Application Server Version 7.x deployment manager profile. Example: /opt/IBM/WebSphere7/profiles/DMgr01
  2. Migrate the application server related configuration from Version 7 to Version 8.
    1. Change the directory to: <WXS_v8_install_root>/bin.
    2. Run the following command: 
      xsmigration.bat|sh -targetwashome <WAS8x_HOME> 
-sourcewashome <WAS7x_HOME> -targetprofilepath <WAS8x_AppServerProfile>
 -sourceprofilepath <WAS7x_AppServerProfile>
      where
      • <WAS8x_HOME> is the root location of the WebSphere Application Server Version 8.x installation. Example /opt/IBM/WebSphere8
      • <WAS7x_HOME> is the root location of the WebSphere Application Server Version 7.x installation Example:/opt/IBM/WebSphere7
      • <WAS8x_AppServerProfile> is the location of the WebSphere Application Server Version 8.x application server profile. Example: /opt/IBM/WebSphere8/profiles/AppServer01
      • <WAS7x_AppServerProfile> is the location of the WebSphere Application Server Version 7.x application server profile. Example: /opt/IBM/WebSphere7/profiles/AppServer01
  3. Restart the WebSphere Application Server Version 8 deployment manager and synchronize all the managed nodes.
