Which upgrade workflow should I use?
There are two workflows you can follow to upgrade BIG-IQ® Centralized Management Logging Node cluster. Before you start the upgrade process, decide which workflow is appropriate for you.
- To preserve the data collected with the current version of BIG-IQ Logging Node, use the work flow in this guide (BIG-IQ® Centralized Management: Upgrading Logging Nodes to Version 5.2 While Preserving Existing Data.
- If you just want to upgrade, and do not care about your data, use F5® BIG-IQ® Centralized Management: Upgrading Logging Nodes to Version 5.2 Without Preserving Existing Data
How do I upgrade my Logging Node cluster to version 5.2 and preserve my existing data?
A Logging Node cluster is made up of all of your Logging Nodes, the BIG-IQ® Centralized Management device you use to manage them, and any BIG-IQ peer devices. If you use a Logging Node cluster to store and manage your alerts and events, there are additional steps in the upgrade process.
The diagram illustrates the process workflow:

Logging Node preparation options
Before you start the upgrade, there are a few tasks to do. To make sure that this process goes smoothly, F5 provides a script that automates the preparation process. You can either run this script, or perform the preparation tasks yourself.
The diagram illustrates these two work flows, automated on the left:
