Migrating a Version 5.x application server to a Version 6.0.x standalone application server with the Migration wizard

Use the Migration wizard to migrate from a WebSphere Application Server Version 5.x application server to a Version 6.0.x standalone application server.

Before you begin

Collect the following information about your Version 5.x installation before you begin this procedure. The Migration wizard prompts you for the information during the migration:
  • Installation root directory

    See WASPreUpgrade command for a description of the currentWebSphereDirectory parameter.

  • Use port values assigned to previous installation?

    Specifying “true” causes any ports of matching VirtualHosts to first be removed from the new configuration before adding the new values.

    Specifying “false” for this parameter will just add new port values.

    See WASPostUpgrade command for a description of the replacePorts parameter.

  • Backup directory name

    See WASPreUpgrade command for a description of the backupDirectory parameter.

  • Target profile name.

    See WASPostUpgrade command for a description of the profileName parameter.

Before using the Migration wizard, you should have installed Version 6.0.x already. Use the Profile creation wizard to create a valid new application server profile if one does not already exist. After verifying that a valid Version 6.0.x target exists, you can start the procedure.

The Network Deployment product does not create a profile during installation because there are three profile types. The Installation wizard prompts you to create a profile, but that action is optional during installation. Create a standalone application server profile if you have not already created one.

About this task

This article describes using the Migration wizard to migrate a Version 5.x application server to a Version 6.0.x standalone application server. Use the Migration wizard after installing Version 6.0.x and creating the required standalone application server profile.

The Migration wizard is new as of Version 6.0. The wizard is the graphical interface to the Version 6.0.x migration tools, which are the WASPreUpgrade command and the WASPostUpgrade command. The migration tools are command-line tools.

Use the wizard to migrate a Version 5.x application server to a Version 6.0.x standalone application server.

Procedure

  1. Start the First steps console.
    • [Linux] ./profile_root/firststeps/firststeps.sh
    • [Windows] profile_root\firststeps\firststeps.bat
  2. When migrating a standalone application server from Version 5.1.0 or earlier Version 5.x releases only: Look for and delete the app_server_root/properties/version/ND.product file if the file exists.

    The file is created if the standalone application server was ever federated into a deployment manager cell. Version 5.1.1 deletes the file when a node is unfederated. Earlier versions do not. The Migration wizard reacts to the presence of the file by identifying the standalone node as a federated node. If the node names do not match, an erroneous failure occurs.

    See Migrating a Version 5.x application server to a Version 6.0.x standalone application server profile after unfederating the Version 5.x node fails with a node name mismatch error for more information.

  3. Click Migration wizard on the First steps console.

    The First steps console starts the Migration wizard. The wizard displays its Welcome panel.

  4. [AIX] [Solaris] [Version 6.0.2] Click Exit on the First steps console.
  5. Read the Welcome panel of the Migration wizard to learn about the migration, then click Next.

    The wizard displays the detected versions of WebSphere Application Server panel.

  6. Select a previous version, then click Next to continue.

    Select the check box to specify the location of a previous installation that might not appear in the list.

    If the previous version specification is correct, the wizard displays the Target profile selection panel.

  7. Specify a backup directory, then click Next to continue.

    If the Version 6.0.x profile is valid, the wizard displays the Target profile selection panel.

  8. Select the target profile from the list of valid Version 6.0.x profiles for the installation, then click Next.

    Use the Profile creation wizard to create a target profile for the migration if one does not yet exist.

    The wizard displays the Port value assignment panel.

  9. Choose whether to use port values assigned to the previous installation, or generate new Version 6.0.x port values that are already assigned to the target profile, then click Next.

    The wizard begins the premigration. The wizard displays a Migration status panel during the premigration.

    If the premigration is not successful, the wizard displays a failure panel. If the premigration is partially successful, the wizard displays a warning panel.

    Correct any problems and retry the migration.

    If the premigration is successful, the wizard displays an indication of success.

  10. Click Next to start the postmigration.

    If the postmigration is not successful, the wizard displays a failure panel. If the postmigration is partially successful, the wizard displays a warning panel.

    Correct any problems and retry the migration.

    If the postmigration is successful, the wizard displays an indication of success.

  11. Click Finish to exit the Migration wizard.
