Migrating a z/OS standalone application server: Checklist

Activities for migrating a standalone application server to WebSphere® Application Server Version 7.0 after you generate the appropriate Job Control Language (JCL) jobs include activities related to general preparation, transaction-log clearance, and node migration. Use the following checklist as a quick reference to these activities. Follow the instructions that were generated by the z/OS® Migration Management Tool or the zmmt command to complete the process of migrating your standalone application server to Version 7.0.

Before you begin

You can find more details about migrating a standalone application server in Preparing to migrate a z/OS standalone application server and Migrating a standalone application server on the z/OS® operating system.

About this task

Key similarities to migrating a deployment manager:
  • You must still create CNTL and DATA datasets.
  • You must still allocate and mount a new configuration file system to act as the target for the new Version 7.0 configuration, either manually or using the BBOMBHFS or BBOMBZFS job.
  • You must still run the BBOWMG3B job to perform the migration.
Key differences from migrating a deployment manager:
  • You must clear the transaction logs using the BBOWMG1B job; you do not have to complete this step for a deployment manager migration.
  • You must disable Peer Restart and Recovery (PRR) mode using the BBOWMG2B job; you do not have to complete this step for a deployment manager migration.
  • There is no deployment manager node to migrate.

    __________ Create the Version 7.0 configuration mount point, allocate a configuration file system, and mount either manually or using the BBOMBHFS or BBOMBZFS job.
    __________ Run the BBOMBCP job to copy the generated JCL procedures to your procedure library.
  2. Clear the transaction logs for the application server node.

    __________ Run the BBOWMG1B job, and check for success.
    __________ Restart the application server to clear the transaction logs.
    __________ Run the BBOWMG2B job to disable PRR mode.
  3. Migrate the application server.
