Migrating a standalone application server: Checklist

Activities for migrating a standalone application server to WebSphere Application Server Version 6.1.x after you generate the appropriate JCL jobs include activities related to general preparation, transaction-log clearance, and node migration. This checklist is intended to provide a quick reference to these activities. Follow the detailed instructions that were generated when you created your migration jobs to complete the process of migrating your standalone application server to Version 6.1.x.

Before you begin

You can find more details in Preparing to migrate a standalone application server and Migrating a standalone application server.

About this task

Key similarities to migrating a deployment manager:
  • You must still create CNTL/DATA data sets.
  • You must still allocate and mount a new configuration file system to act as the target for the new Version 6.1.x configuration, either manually or using BBOMBHFS or BBOMBZFS.
  • You must still run BBOWMG3B to perform the migration.
Key differences from migrating a deployment manager:
  • You must clear the transaction logs using BBOWMG1B; you do not have to do this for a deployment manager migration.
  • You must disable PRR mode using BBOWMG2B; you do not have to do this for a deployment manager migration.
  • There is no deployment manager node to migrate.

Procedure

  1. Prepare to migrate the application server.
    Check off Item
      Make sure that you have a minimum level of Version 6.1.x maintenance.

    See Overview of migration, coexistence, and interoperability.

      Inventory your existing Version 5.x or 6.0.x configuration and capture key information.

    See Preparing to migrate a standalone application server.

      Create CNTL/DATA data sets for each node to be migrated.

    See Creating a definition for migrating a standalone application server using the z/OS Migration Management Tool.

    See Migrating a standalone application server: Customization Dialog walk-through.

      Create theVersion 6.1.x configuration mount point; allocate a configuration file system, and mount either manually or using BBOMBHFS or BBOMBZFS.
      Run BBOMBCP to copy the generated JCL procedures to your procedure library.
  2. Clear the transaction logs for the application server node.
    Check off Item
      Stop the server in the standalone application server node.
      Run BBOWMG1B, and check for success.
      Restart the application server to clear the transaction logs. It will start and then automatically stop.
      Run BBOWMG2B to disable PRR mode.
  3. Migrate the application server.
    Check off Item
      Ensure that all servers are stopped, including the daemon server.
      Run BBOWMG3B, and check for success.
      Start the application server.
