This section compares the pre/post-upgrade operational state using the CLI.
For software upgrade operations, the Avi Load Balancer Controller provides visibility into the pre-operation and post-operation states of the system, summarizing and highlighting the significant differences in the state or health of the system caused by the performed operation.
When performing a software upgrade, the Avi Load Balancer Controller will take an operational state snapshot pre-upgrade and another post-upgrade to allow the admin to perform a quick validation of the current state of their environment compared to the state before the upgrade.
The operational snapshots are taken for the following objects:
Virtual Services
Service Engines
Pools
GSLB Services
The operational snapshots are taken during the following software operations:
Upgrade
Patch
Rollback Patch
Compare Pre/Post Upgrade Operational State using the CLI
The following are the steps to compare pre/ post upgrade operational state using the CLI:
Check if all the state-diff operations exists in the system.
