FAQs: BIG-IQ Upgrade to 8.1.0
Versions 7.0.x–8.0.x are supported for upgrade to 8.1.0
Depending on your configuration and the number of devices you are managing, this could take approximately 45-60 minutes per device. For example, if you have one BIG-IQ device with three DCDs (total 4), the maximum upgrade time is 4 hours.
When the BIG-IQ primary device upgrades, it becomes briefly inaccessible (time varies depending on your system). When you can log in to the BIG-IQ again, the device upgrade process is complete.
Warning: In the event that the system is unavailable for longer than 60 minutes, or the upgrade fails, generate a QView and report the issue at support.f5.com .
Even though you can log in to the BIG-IQ system after the software is installed, the system continues the post-upgrade process, which includes re-indexing in the background. The time required for re-indexing varies, depending on the size of your system configuration.
