Completing Post-Upgrade Tasks
What are the post-upgrade tasks?
Once you have upgraded the BIG-IQ system with a DCD cluster, you need to:
- Add the secondary BIG-IQ to the primary BIG-IQ.
- Re-discover devices and re-import services.
- Re-discover devices and re-import LTM, ASM, AFM, and DNS services in bulk using a script.
-
Upgrade applications to enable statistics visibility (relevant only to upgrades from BIG-IQ version 5.4)
- Use a script to remove and recreate access groups in bulk for devices running APM services.
-
Re-import access groups (without SWG data) from the user interface for devices running APM services.
-
Remove and recreate access groups (without SWG data) from the user interface for devices running APM services.
Add the secondary BIG-IQ system to the primary BIG-IQ system
Even though you can log in to the secondary BIG-IQ after the you re-establish the HA configuration, the system continues some database re-indexing processes in the background. For larger configurations, that can take up to an hour. If you perform any searches on objects before it's done re-indexing, BIG-IQ might not return the expected results.
After the HA configuration is re-established, you'll be automatically logged out of the primary BIG-IQ system for a few minutes while the secondary BIG-IQ system restarts.
After the secondary system restarts, you can log back into the primary BIG-IQ system.
