Parallel upgrade from version 9.4.0.x to version 9.5.0.x or 10.2.x

Detailed steps to perform a parallel upgrade from version 9.4.0.x to version 9.5.0.x or 10.2.x

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

Most 9.4 environments are not configured with SSL, which is enabled by default starting from version 10.1. To ensure communication between all components, you need to perform a short procedure, as described in Can I install a backup master domain manager at version 10.2.2 in a back-level environment?. You also need to enable TLS version 1.2 on the back-level master domain manager so that the dynamic agent on the new backup master domain manager can communicate with the back-level master domain manager. For the complete procedure, see How can I get the dynamic agent installed on the new backup master domain manager to communicate with the back-level master domain manager?.

If you are using default certificates in your current environment, before you start the upgrade, ensure you convert the certificates from the .jks to the .pem format and copy them to the workstations where you plan to install the server components and the Dynamic Workload Console. For the complete procedure, see Converting default certificates.

Note: If one or more components are installed on RHEL 9 or later, implement the workaround described in Installation or upgrade fails on RHEL version 9 and later before getting started.
To perform a parallel upgrade from version 9.4.0.x to version 9.5.0.x or 10.2.x perform the following steps:
  1. Installing WebSphere Application Server Liberty on the workstations hosting the Dynamic Workload Console and the server components (dynamic domain manager and its backups, master domain manager and its backups). 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
  6. Upgrading domain managers. Because domain managers are agents, you can find the procedure in Upgrading agents and domain managers
  7. Upgrading the database schema for the dynamic domain manager
  8. Installing a dynamic domain manager instance and its 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)
  9. Upgrading the database schema for the server components
  10. Installing the new master domain manager configured as a backup
    1. Ensuring communication in your environment
    2. Configuring security
    3. Switching the master domain manager to the new backup master
    4. Making the switch manager permanent
    5. Customizing and submitting the optional FINAL job stream
  11. Installing a new backup master domain manager
    1. Installing a new backup master domain manager
    2. Configuring security
    3. Uninstalling the back-level backup master domain manager
  12. Upgrading agents and domain managers
  13. Enabling product encryption after upgrading
