Upgrading to BIG-IQ version 8.2.0.1

You can upgrade directly to BIG-IQ version 8.2.0 from version 7.x or later. If your BIG-IQ deployment is currently running a version earlier than version 7.x, you will need to perform an incremental upgrade. Refer to Supported upgrade paths for supported upgrade information.

The upgrade includes a set of pre-upgrade tasks, the upgrade itself, and a set of post-upgrade tasks. It is recommended that you review the pre-upgrade tasks in advance of your scheduled upgrade date. During the upgrade, the maintenance window begins once you begin the upgrade itself, and depends on your current BIG-IQ setup, configuration, and managed BIG-IP devices. The upgrade process can take up to several hours depending on the number of devices in your setup. It is important that you not interrupt the installation process by restarting services or the server.

During the post-upgrade process, you can use your BIG-IQ devices as needed. However, due to system-reindexing in the post-upgrade process, some services may continue to be limited after your primary BIG-IQ device completes the upgrade.
