Parallel upgrade from version 9.4.0.x to version 9.5.0.x or 10.1.0.x

Detailed steps to perform a parallel upgrade from version 9.4.0.x to version 9.5.0.x or 10.1.0.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 Q: Can I install a backup master domain manager at version 10.1 Fix Pack 5 in a back-level environment?

To perform a parallel upgrade from version 9.4.0.x to version 9.5.0.x or 10.1.0.x perform the following steps:
  1. Installing WebSphere Application Server Liberty Base 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

  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. Configuring security
    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
  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
