[z/OS]

Planning to migrate product configurations

You must prepare your system to migrate from WebSphere Application Server for z/OS Version 5.x and Version 6.0.x to Version 6.1.x.

Before you begin

WebSphere Application Server for z/OS supports migration paths to Version 6.1.x from the following releases:
  • Version 5.0.x
  • Version 5.1.x
  • Version 6.0.x
In addition to migration, it is possible for these WebSphere Application Server versions to coexist with Version 6.1.x.
Restriction: Version 5.0.x cannot coexist with Version 6.x in the same cell on the same LPAR. If you have multiple Version 5.0.x nodes on the same LPAR, all nodes must be migrated to Version 6.1.x at the same time.

To learn more about the migration utilities, see Overview of migration, coexistence, and interoperability. When you are getting ready to migrate to Version 6.1.x, see Premigration considerations and Migrating standalone application servers, Migrating Network Deployment configurations, or Migrating federated nodes for detailed planning and migration information.

Procedure

  1. Install the Version 6.1.x product.
  2. Review the "Ensuring problem avoidance" article in the information center, making sure that each task has been completed before you begin.
  3. Review Migrating and coexisting to determine whether you want the two versions of the product to coexist in the same environment or you want to perform a complete migration.
  4. Capture the variables used in the current installation.

    This information will be useful in planning for the new installation, ensuring that you define unique ports, and planning for the configuration file system structure.

What to do next

When you are ready to begin migrating, go to Migrating product configurations.
