In this post I will walk through steps of upgrading a clustered vRLI deployment. Before preparing for upgrade, make sure to read VMware documentation for the supported upgrade path.
One very important consideration before you start upgrading vRLI:
Upgrading vRealize Log Insight must be done from the master node’s FQDN. Upgrading using the Integrated Load Balancer IP address is not supported.
To start vRLI upgrade, login to the web interface of master node and navigate to Administration > Cluster and click on Upgrade Cluster button.
