Migrating the deployment manager for z/OS

After you have prepared your cells for migration and ensured that you have met all prerequisites, migrate the deployment manager.

Before you begin

To Migrate WebSphere® Extended Deployment Compute Grid Version 6.1.1 or above to Version 8.5, you must have WebSphere Extended Deployment Compute Grid Fixpack 3 and cumulative interim fix PM39203 installed. Migration from any version of the Feature Pack for Modern Batch 1.0.0.x is supported.

About this task

You must migrate the deployment manager first. To migrate the deployment manager, perform the following steps:

Procedure

  1. Backup your modern batch configuration on the deployment manager node. Use the provided migrateWCGConfigTo85.py script to export the configuration data. After the migration is completed, you will use this script again to restore your configuration, which automatically makes all necessary changes to convert between releases. Change directories to your cell’s deployment manager configuration file-system, and execute:
    ./bin/wsadmin.sh -lang jython -f migrateWCGConfigTo85.py \
    --backup [-configBackupDir /path/to/backup/location]
  2. Install WebSphere Application Server Version 8.5.
  3. Migrate your old deployment manager to WebSphere Application Server Version 8.5. You can use the migration tools to migrate your old deployment manager to Version 8.5.
  4. Use the --wasmigrate option of the migration script. For example:

    Perform --wasmigrate on your migrated Dmgr (from its WAS_HOME/bin dir)

    wsadmin.sh -conntype NONE -lang jython -f .migrateConfigTo85.py --wasmigrate -oldWASHome
     <oldWASHome> -newWASHome <newWASHome> -cellName <cell> -nameOfProfile <profile>
     -configBackupDir <PathToBackupLocation> -level <level>
  5. Ensure the previous version Compute Grid or Feature Pack nodes are stopped.
  6. Start the new deployment manager.
  7. Restore your saved configurations on the deployment manager. To restore a configuration, run the following script:
    ./bin/wsadmin.sh -lang jython -f migrateWCGConfigTo85.py \
    --restore [-configBackupDir /path/to/backup/location]
    Avoid trouble Avoid trouble: The configuration now stored in your deployment manager is incompatible with your non-migrated nodes at this time. Do not synchronize your nodes until after you have finished migrating them. Do not restart any non-migrated servers and node agents after this point.gotcha
