Migrating the product

Migrating involves collecting the configuration information from a previous release of the product, and merging that information into a configuration for a new release. Use this procedure to migrate from WebSphere Extended Deployment Version 6.0.2 to WebSphere Extended Deployment Version 6.1.

Before you begin

The documentation is designed to provide instructions on migrating to a WebSphere® Extended Deployment Version 6.1 installation that includes all three product components: Operations Optimization, Compute Grid, and Data Grid.

The process for migrating supports only the following two existing installations:
  • WebSphere Extended Deployment Version 6.0.2 installed on WebSphere Application Server Network Deployment Version 6.0.2
  • WebSphere Extended Deployment Version 6.0.2 installed on WebSphere Application Server Network Deployment Version 6.1
While both environments are supported, the steps to migrate from each type of existing installation are slightly different. For more information about the differences, refer to the detailed migrating steps.

Ensure that the cell and the nodes have the same name to successfully migrate from Version 6.0.2 to Version 6.1. Also, userid and password are optional parameters that should always be specified with the XDUpgrade command when migrating products from the command line. Because the migration utility does not check for these parameters, the migration will fail if the administrator user ID and password are not specified when security is enabled on the workstation.

About this task

WebSphere Extended Deployment Version 6.1 introduces new concepts that help provide a simple process for migrating the product from Version 6.0.2 to Version 6.1. In previous releases, the deployment manager and all of the nodes were migrated all at once, which required the entire cell to temporarily shut down during the migration process. In Version 6.1, a more simplified strategy consists of using a rolling migration in which you first migrate the deployment manager, and then migrate each node one at a time. This strategy results in the creation of a mixed cell environment, which is a cell that contains nodes that are operating at both the 6.0.2 product level and the 6.1 product level. Since the Version 6.0.2 cell still exists in the environment at the same time that the new Version 6.1 cell is being created, you must ensure that your workstation has a sufficient amount of drive space to support the mixed cell environment.

A third concept introduces the capability to migrate Version 6.0.2, which must already exist on WebSphere Application Server Network Deployment Version 6.1, directly to Version 6.1. In other words, you are not required to install or migrate Network Deployment as a prerequisite for migrating Version 6.0.2 to Version 6.1. This task is not available with an installation of Version 6.0.2 on WebSphere Application Server Network Deployment Version 6.0.2. For more information on the migration capabilities featured in Version 6.1, refer to each of the following items:

Procedure

  1. Read about the tools that are available to migrate existing product configurations. The tools that you can use are included in the following list:
    • The Migration wizard migrates WebSphere Extended Deployment Version 6.0.2 to Version 6.1 through a graphical user interface (GUI). See Using the Migration wizard for more information.
    • The XDPreUpgrade command saves the configuration of WebSphere Extended Deployment Version 6.0.2 installed on WebSphere Application Server Network Deployment Version 6.1 into a migration-specific backup directory. See XDPreUpgrade command for more information.
    • The XDUpgrade command restores the configuration data from WebSphere Extended Deployment Version 6.0.2. See XDUpgrade command for more information.
  2. Migrate to a Version 6.1 deployment manager. See Migrating to a Version 6.1 deployment manager for more information.
  3. Migrate to a Version 6.1 node. See Migrating to a Version 6.1 node for more information.
  4. Refer to the table that lists the required tasks to complete a successful migration and where to perform the tasks. See Where migration tasks are performed for more information.

What to do next

Complete the migration process by using the Migration wizard or the XDUpgrade utility. The wizard is the graphical interface to the primary Version 6.1 migration tools, the XDPreUpgrade and the XDUpgrade commands.
