BIG-IQ Centralized Management
Upgrading BIG-IQ with a Data Collection Device from Version 8.0.x with Minimal Downtime
What is a minimal
- 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.
Upgrading BIG-IQ version 8.0.x with a data collection device
cluster to version 8.1.0 with minimal
What BIG-IQ setup does this upgrade process support?
What happens during a BIG-IQ upgrade to version 8.1.0?
- 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.

BIG-IQ pre-upgrade checklist
- 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.

Summary of tasks to upgrade a BIG-IQ system with data collection
devices with minimal downtime
- Download the BIG-IQ software image from the F5 Downloads site.
- Upload the BIG-IQ software image to BIG-IQ.
- Confirm alerts and events can be sent to an alternative device in the data collection device cluster.
- Upgrade the primary BIG-IQ and the data collection devices to the latest version.
- Upload the software image to the secondary BIG-IQ system.
- Manually upgrade the secondary BIG-IQ system.
- Add the secondary BIG-IQ system back to the primary BIG-IQ system.
- Re-discover devices and re-import services.
