If a Splunk Operator release includes an updated Splunk Enterprise Docker image, the operator upgrade will also initiate pod restart using the latest Splunk Enterprise Docker image.

At each step, if a particular CR instance exists, a certain flow is imposed to ensure that each instance is updated in the correct order. After an instance is upgraded, the Operator verifies if the upgrade was successful and all the components are working as expected. If any unexpected behaviour is detected, the process is terminated.

+3. The Splunk Operator adheres to the upgrade path steps delineated in the Splunk documentation. Pod termination and redeployment occur in a specific order based on the recommended upgrade path.
+4. Standalone or License manager will be the first to be redeployed
+5. Next ClusterManager pod will be redeployed, next the Monitoring Console pod undergoes termination and redeployment.

+7. Afterwards, all pods in the Indexer cluster are redeployed sequentially. In cases where multi-zone Indexer clusters are utilized, they undergo redeployment zone by zone.
+8. Each pod upgrade is meticulously verified to ensure a successful process, with thorough checks conducted to confirm that everything is functioning as expected.
