Migrating application server nodes for z/OS

You can migrate your WebSphere® Extended Deployment Compute Grid or Feature Pack for Modern Batch servers to WebSphere Application Server Version 8.5.

Before you begin

About this task

Migrate the schedulers one at a time and then migrate the endpoints. Repeat the following steps for each Compute Grid or batch server:

Procedure

  1. Stop the servers.
  2. Install WebSphere Application Server Version 8.5.
  3. Migrate your old application server nodes to WebSphere Application Server Version 8.5. You can use the migration tools to migrate your old deployment manager to Version 8.5.
  4. Start the node agent and wait for it to synchronize.
  5. Synchronize and start the Job Scheduler servers.
    Avoid trouble Avoid trouble: Do not start endpoint servers.gotcha
    Log into your administrative console and ensure the newly migrated node is properly synchronized with the deployment manager. Start the Job Scheduler servers on the node.
  6. Run the restore command for the scheduler. For example:

    Change directories to your scheduler node profile bin dir, and run restore for the scheduler

    wsadmin -lang jython -f migrateConfigTo85.py --restore -nameOfProfile <profile>
     -configBackupDir <PathToBackupLocation> -node <scheduler_node_name>
  7. Stop all other Job Schedulers on all other nodes. You must stop all non-migrated Job Schedulers.
    Note: This action will put your configuration into a state where it is no longer highly available. If you are approaching a scheduled critical batch window, consider backing up your work and restoring the production environment.
  8. Start the migrated endpoint server. When the migrated job scheduler server is the only job scheduler running, you can start the migrated endpoint server. It will co-exist with all other currently running endpoint servers.

What to do next

Migrate the remaining nodes. For each remaining node:
  1. Stop all servers running on that node.
  2. Start the node agent and restore the batch configuration.
  3. Synchronize the node with the deployment manager.
  4. Start any job scheduler and end point cluster members on the node.
