The issue is due to insufficient resources for the ade-platform-namespace namespace on the cluster

Since the cluster namespace does not have the required resources (CPUs Core and RAM) hence the prometheus-entity-reconciler-service is failing

Please ensure the cluster is having resources available to allocate the required resources (CPUs Core and RAM) to the namespace on which the BMC Helix Service Monitoring (AIOPs) on-prem is deployed - ade-platform-namespace.

Please refer to the "Namespace resource requirements" documentation and update the namespace resources accordingly, to update the resource quota please use - "kubectl edit resourcequota"

Once resource requirements are met, please try to perform the upgrade again

If the issue persists then please open a support case and share "helix-on-prem-deployment-manager/logs/deployment.log" file
