Upgrading to BIG-IQ Version 8.1.0
Supported upgrade paths
You can upgrade to BIG-IQ version 8.1.0 from the following BIG-IQ versions and deployments:
- BIG-IQ versions 6.0.x and later without a data collection device cluster. For more information, see Upgrading BIG-IQ from version 6.0.0 and later.
- BIG-IQ versions 6.0.x and later with a data collection device cluster, regular upgrade process (statistics collection downtime during device upgrade). For more information, see Upgrading BIG-IQ version 6.0.0 and later with a Data Collection Cluster.
- BIG-IQ version 8.0.x and later with a data collection device cluster, minimal downtime for statistics collection (rolling data collection device upgrade). For more information, see Upgrading BIG-IQ with a Data Collection Device Cluster with Minimal Downtime.
Upgrading to BIG-IQ version 8.1.0
You can upgrade directly to BIG-IQ version 8.1.0 from version 6.0.x or
later. If your BIG-IQ deployment is currently running a version earlier than version 6.0.x,
you will need to perform an incremental upgrade. Refer to Supported upgrade paths for supported
upgrade information, and links to full documentation.
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.
Upgrading an existing BIG-IQ with a single NIC to version 8.1.0 is not currently supported.
Upgrading BIG-IQ with a Data Collection Device
cluster
A minimal downtime (rolling) upgrade to BIG-IQ version 8.1.0 is supported only from version 8.0.x. The rolling upgrade process allows you to maintain statistics collection almost throughout the entire upgrade process.
A regular (non-rolling) upgrade means that during the upgrade maintenance window, statistics collection
is temporarily suspended in BIG-IQ deployments with data collection devices (DCDs). The
length of time for which data collection is suspended depends on the following:
- The number of devices in your system configuration
- The number of BIG-IP services managed by your BIG-IQ deployment
- The volume of statistics and data stored on BIG-IQ prior to the upgrade
The BIG-IQ upgrade process takes approximately 45-60 minutes per
device. For example, a BIG-IQ deployment with an single BIG-IQ device and 3 DCDs (4
devices total) will require a maintenance window of up to four hours to complete to
upgrade process. Statistics collection is suspended during this process, but resumes
immediately after upgrade completion.
Following the upgrade (including version 8.1.0.1), you must re-discover and re-import all managed devices and services to ensure new data is collected. For more information, see Re-discover and re-import BIG-IP devices.
The
post-upgrade process can take several hours. During this time, you have access to
your system, but may have limited visibility into your historical statistics. Once
the post-upgrade process is complete, historical statistics display as
expected.
Upgrading BIG-IQ (no data collection)
When upgrading the primary BIG-IQ device, either stand-alone or in
an HA pair, there is a maintenance window of up to 60 minutes. During this time, you
will not have access to system services. Services resume when you log back
onto BIG-IQ after a successful upgrade.
