Performing a direct upgrade from v 9.5.0.x or v 10.x.x to v 10.2.3

Detailed steps to perform a direct upgrade from version 9.5.0.x or v 10.x.x to version 10.2.3

To upgrade your environment using a direct upgrade procedure, perform the following steps:
  1. Upgrading WebSphere Application Server Liberty on the workstations hosting Dynamic Workload Console and the server components (dynamic domain manager and its backups, master domain manager and its backups). You can also optionally move from WebSphere Application Server Liberty Base to Open Liberty.
  2. Performing a direct upgrade of the Dynamic Workload Console and its database
  3. Performing a direct upgrade of the dynamic domain manager, its backups, and their database
  4. Performing a direct upgrade of the backup master domain manager and its database
    1. Switching the master domain manager to the upgraded backup master
    2. Making the switch permanent
  5. Performing a direct upgrade of the master domain manager
    1. Switching back to the master domain manager from the backup master domain manager
    2. Making the switch permanent
  6. Upgrading agents and domain managers
Environment with custom certificates
If you have version 9.5 installed with custom certificates, then after upgrading to 10.2 you must ensure that the parameters and the name of the relevant certificates in the localopts file are correct.
If you have previously used certificates generated with OpenSSL, check the paths in the following section:
  • For Open SSL, check:
    • SSL key
    • SSL certified
    • SSL key pwd
    • SSL CA certified
    • SSL random seed
If you have used GSKit, the relevant parameters are automatically migrated to the new OpenSSL parameters:
  • SSL Version
  • SSL Ciphers
  • CLI SSL Ciphers
  • CLI SSL Version

If the value of these fields corresponds to an incorrect path, then stop the WebSphere Application Server Liberty Base, make the necessary changes, and refer to the client's certificates, and then Restart.
