Planning to migrate product configurations for z/OS

You must prepare your system to migrate from WebSphere® Application Server for z/OS® Version 5.1.x and Version 6.x to Version 7.0.

Before you begin

WebSphere Application Server for z/OS supports migration paths to Version 7.0 from the following releases:
  • Version 5.1.x
  • Version 6.x
In addition to migration, it is possible for these WebSphere Application Server Version 7.0.

To learn more about the migration utilities, read Overview of migration, coexistence, and interoperability. When you are getting ready to migrate to Version 7.0, read Premigration considerations and Migrating z/OS standalone application servers, Migrating WebSphere Application Server, Network Deployment configurations on the z/OS® operating system, or Migrating federated nodes for z/OS for planning and migration information.

Procedure

  1. Read the "Task overview: Installing" article in the information center.

    This document will give you a basic understanding of what is involved with installing the product.

  2. Install the Version 7.0 product.
    Read the following articles in the information center for details:
    • Planning for installation
    • Installing the product and additional software
  3. To learn about preparing your environment for migration, read the "Preparing the base operating system" article in the information center.
    You should also plan for any new features that you might want to include. Use the instructions and tips:
    • For system requirements, read the "Hardware and software requirements on z/OS" article in the information center.
    • For server security (RACF®), read the "Security planning overview" article in the information center.
    • For workload management (WLM), read the "Workload management (WLM) for z/OS" article in the information center.
  4. Review the "Ensuring problem avoidance" article in the information center, making sure that each task has been completed before you begin.
  5. Review Migrating and coexisting application servers 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.
  6. 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.
