Parallel upgrade from version 9.4.0.x to version 10.2.3

Detailed steps to perform a parallel upgrade from version 9.4.0.x to version 10.2.3

A number of major product improvements have been inserted starting from version 9.5. For this reason, when upgrading from version 9.4.0.x, you have to perform a fresh installation of the following components and prerequisites:
  • WebSphere Application Server Liberty Base
  • Dynamic Workload Console
  • Dynamic Workload Console database
  • master domain manager
  • backup master domain manager
  • dynamic domain manager
  • backup dynamic domain manager
Before you start the upgrade, ensure you have performed the following procedures:
  • Connecting the Dynamic Workload Console to a new node or database. If you are currently using Derby, install a supported database before exporting Dynamic Workload Console data. This is necessary because Derby is no longer supported as of version 10.2.3.
  • Installing the fix for APAR IJ47731 on the master domain manager. To obtain the fix for your product version, contact Software Support.
  • Configuring TLS to the appropriate version on the 9.4 master domain manager to ensure communication in your environment.
  • Converting default certificates, if you are using default certificates in your current environment. Use this procedure to convert the certificates from the JKS to the PEM format, then copy them to the workstations where you plan to install the server components (dynamic domain manager and its backups, master domain manager and its backups) and the Dynamic Workload Console.
    Certificates are now required when installing or upgrading HCL Workload Automation. You can no longer install nor upgrade HCL Workload Automation without securing your environment with certificates. The required certificates are:
    • ca.crt
    • tls.key
    • tls.crt
    For UNIX systems, ensure that all the files have the ownership of the user who installed the master domain manager and the correct permissions (644).
  • Install the latest fix pack for version 9.4 on all workstations in your environment.
To perform a parallel upgrade from version 9.4.0.x to 10.2.3, perform the following steps:
  1. Installing WebSphere Application Server Liberty on the workstations hosting the Dynamic Workload Console and the server components. This is a prerequisite component which replaces WebSphere Application Server used in version 9.4.0x.
  2. Encrypting passwords (optional)
  3. Creating and populating the database for the Dynamic Workload Console
  4. Installing the Dynamic Workload Console
  5. Creating the HCL Workload Automation administrative user on the workstations which will host the components at 10.2.3 level.
  6. Upgrading the database for the server components
  7. Installing a new dynamic domain manager configured as a backup
    1. Installing a new dynamic domain manager configured as a backup
    2. Switching the dynamic domain manager to the new dynamic domain manager configured as backup
    3. Installing a new backup dynamic domain manager to replace the backup dynamic domain manager which you have switched to become the current dynamic domain manager.
    4. Switching back to the old dynamic domain manager (optional)
  8. Installing the new master domain manager configured as a backup
    1. Ensuring communication in your environment
    2. Switching the master domain manager to the new backup master
    3. Making the switch manager permanent
    4. Customizing and submitting the optional FINAL job stream
  9. Installing a new backup master domain manager
    1. Installing a new backup master domain manager
    2. Uninstalling the back-level backup master domain manager
  10. Upgrading agents and domain managers
