See sections titled:
"Software Packages Supported with Specific CABI Versions" and "CABI Support Matrix"
For a more detailed, stepwise description to implement the cabi upgrade, please follow the steps below:
Pre-cabi install/upgrade: If cabi was previously installed on the cabi server robot, first follow the cabi cleanup KB Article:
Cabi cleanup process for uninstallation or reinstall
https://knowledge.broadcom.com/external/article?articleId=271552
Stepwise instructions:
In the wasp probe on the cabi server robot, via Raw Configure mode, correct the data_engine probe,‘NimBUS’ address key, e.g., /<UIM_domain>/<Primary_hub>/<robot>/data_engine
Deactivate wasp
Wait for the port and the PID to disappear
Activate wasp, and once the wasp is green and has a port and a PID,
Deploy cabi probe v7.50 on the cabi server robot and make sure it starts and gets a port and a PID
Deploy the following report/dashboard packages to the CABI server from your local Primary hub archive:
uim_unified_reporter_pack (v1.10)
uim_cabi_health_report_pack (v1.42)
uim_core_dashboards_pack(v2.51)
7. Deploy the ump_cabi package (v20.48) to the Operator Console server robot.
8. Once wasp and cabi are both green and running fine, then deploy cabi v8.00.
It takes some time for this to complete, and then both wasp and cabi should be green and have ports and PIDs. Check logs for errors.
9. Repeat the above process starting with Step #1, but in Step #5, deploy cabi probe v8.01
10. Login to the CABI portal (http://<cabi_server_IP_Address> or <FQDN>/cabijs/) and check whether it is working or not.
Use the default username and password for CABI Server.
cabi version 8.00 works with DX UIM 20.4 CU4 or higher
cabi version 8.01 works with DX UIM 20.4 CU8 or higher
Upgrading to cabi 8.00 or 8.01 requires cabi 7.50 be in place first, for more info please refer to: CABI Support Matrix
