Upgrading BIG-IQ with a Data Collection Device from Version 8.0.x with Minimal Downtime
What is a minimal
The minimal downtime upgrade process (also referred to as
rolling upgrade) significantly reduces the amount of time your system is offline while you are upgrading to the latest version. The degree to which your BIG-IQ system and DCD cluster can maintain complete online function during upgrade depends on which BIG-IP services you manage, and what kind of data you collect.
- Operators using the BIG-IQ system to review alerts and events might notice slightly slower performance during the upgrade. Data might take a bit longer to refresh, and searches might take a little more time to run.
- You should not lose any ASM events or FPS alerts during the upgrade.
- You should maintain almost all of your AFM events during the upgrade.
- Statistics data is not collected during the upgrade.
- There is a brief downtime (approximately 5 seconds) when the primary BIG-IQ system is upgraded.
- There is another short downtime (less than a minute) when the secondary BIG-IQ is paired with the primary BIG-IQ.

8.1.0with minimal downtime
What BIG-IQ setup does this upgrade process support?
The following upgrade process to BIG-IQ Centralized management version
8.1.0is for system setups that currently have version 8.0.x installed, and include a data collection device cluster with at least three devices. If your system is not currently running version 8.0 and does not include a data collection device cluster with three or more devices, refer to
Upgrading BIG-IQ versions 6.0.0 and later with a Data Collection Device Cluster.
What happens during a BIG-IQ upgrade to version 8.1.0?
This figure represents BIG-IQ in a high-availability (HA) configuration with a data collection device (DCD) cluster. The DCD cluster continues to collect data until you start the upgrade process. Data collection for all BIG-IP devices continues as one DCD at a time is upgraded and restarted. For this example, there are three data collection devices: one has already completed the BIG-IQ DCD upgrade to the latest version, one is undergoing an upgrade, and one is collecting data but still using the pre-upgrade version.
This upgrade procedure with minimal downtime supports BIG-IQ configuration that include a minimum of three data collection devices. However, if the BIG-IQ system you are upgrading includes multiple zones, then in addition to the three DCD minimum, there must also be at least two DCDs in each zone before you can perform a rolling upgrade procedure
Before upgrading F5 BIG-IQ Centralized Management, complete the following.
- Verify the compatibility software on the managed BIG-IP devices.
- Verify licenses and services on upgraded devices.
- Download the BIG-IQ software image.
- Upload the BIG-IQ software image.
- Confirm the required ports are configured correctly on BIG-IQ.
- (For BIG-IQ device HA pairs only) Verify you have access to port TCP 5432.
- Check the disk volume size on your current BIG-IQ installation.
- Check the disk volume size required by the BIG-IQ upgrade.
- Increase the size of the disk volume for the BIG-IQ installation slot (if required).
- Check status of daemons running on BIG-IQ.
- Decide which partition you want to install the new version of BIG-IQ on.
- Download the BIG-IQ pre-upgrade check script.
- Run the BIG-IQ pre-upgrade check tool.
- (For BIG-IQ device HA pairs only) Remove the standby BIG-IQ system pairing.Upgrading an existing BIG-IQ with a single NIC to version 8.1.0 is not currently supported.
Check the status of daemons running on BIG-IQ
Before you install or upgrade BIG-IQ , it's important to take inventory of the status of the running daemons. After you upgrade, you can verify the daemons' state, and make any necessary modifications. To view the daemons, type the following command in the BIG-IQ command line:
admin@(ip-10-1-1-4)(cfg-sync Standalone)(Active)(/Common)(tmos)# show /sys service.
For further information about the daemons that run on BIG-IQ, refer to: https://support.f5.com/csp/article/K14736
BIG-IQ pre-upgrade checklist
To ensure that your upgrade goes smoothly, F5 recommends that you perform a few system checks. Perform this test at least a day or so before you upgrade in case you discover any issues that take longer than expected to resolve. Going through this list ahead of time gives you a chance to resolve any issues before the clock is ticking on your upgrade window.
- Verify that you have completed the pre-upgrade tasks. These are detailed in the articleTasks to complete before you start the upgrade processonsupport.f5.com.)
- Verify that the software version of the BIG-IP devices managed by the BIG-IQ you are updating are at or beyond the minimum supported version. (For details on how to do this, refer to the AskF5 article K34133507 onsupport.f5.com.)
- Depending on the version of BIG-IQ software you are upgrading from, the connectivity requirements for your BIG-IQ system may be different in the version you are upgrading to. Refer to K15612 onsupport.f5.comto confirm that the ports you need are configured correctly.
- If you plan to gather performance Analytics data for the BIG-IP devices managed by the BIG-IQ you are updating confirm that the managed devices are at or beyond version 13.1.1, and provisioned with the AVR service.
- Check that you have sufficient disk space for the upgrade. To calculate the disk space you need, make sure you include the space your current installation consumes and the extra amount needed for the upgrade.If thevarpartition for any of the devices in your cluster was extended before you upgraded, you must extend thevarpartition for that device before the upgrade can succeed.(For details on how to check the size of theThevarpartition needs to be at least 2.5 times larger than it needed to be for earlier BIG-IQ versions.varpartition on your system, refer toCheck the volume sizes on your current BIG-IQ installationandCheck the volume sizes required by the software you want to installinF5 BIG-IQ Centralized Management Disk Space Managementonsupport.f5.com. For details on how to extend a disk volume, refer toResizing VE Disk Volume WorkflowsinF5 BIG-IQ Centralized Management Disk Space Managementonsupport.f5.com).
- Verify that your BIG-IQ VE has sufficient memory and CPUs for the configuration that you plan to deploy. (For details on how to do this, refer toDetermine the resources required for deploymentinPlanning and Implementing a BIG-IQ Centralized Management Deploymentonsupport.f5.com).
- Examine the health of the devices you plan to upgrade. Make sure to inspect the BIG-IQ primary and secondary devices as well as each DCD in the cluster. (For details on how to do this, refer toCheck the health of devices in a DCD clusterinPlanning and Implementing a BIG-IQ Centralized Management Deploymentonsupport.f5.com).
- Re-activate the licenses on the devices you plan to upgrade to make sure that the service contract date is up to date. Make sure to do this for the BIG-IQ primary and secondary devices, as well as each DCD in the cluster. (For details on how to do this, refer to the F5 Knowledge Center articleK15365onsupport.f5.com).
- Confirm the zone configuration of the DCDs that you plan to upgrade and for the devices managed by the BIG-IQ systems you plan to upgrade. If a device is configured to be in a zone that does not have DCDs in it, statistics for that device will not be collected after the upgrade.If the BIG-IQ system you are upgrading includes multiple zones, then in addition to the three DCD minimum, there must also be at least two DCDs in each zone before you can perform a rolling upgrade procedure.
- To view the zone configuration for a DCD, navigate toand note the zone.
- To view the zone configuration for a BIG-IQ system, navigate toDevices, click the name of the device, then clickSTATISTICS COLLECTIONand note the zone.
Check pre-upgrade AS3 version
If the version of AS3 software that is running on the BIG-IQ you are upgrading is newer than the AS3 software version that installs with the upgrade, then you need to note that AS3 version before you upgrade, so you can restore it as part of the post upgrade process.
Steps for determining the pre-upgrade AS3 version are available in the F5 knowledge base article K54909607. Please refer to this article if you are upgrading a BIG-IQ for which a newer version of AS3 software has been installed.
