Administrators should be aware of the following considerations after deploying the Horizontal Pod Autoscaler (HPA):

• If HPA is deployed and you need to upgrade the Oracle Access Management (OAM) container image, then you must delete the HPA before upgrading. To delete the HPA, see Deleting HPA. Once the upgrade is successful you can deploy HPA again.
• If you choose to start/stop an OAM managed server manually as per Scaling OAM Pods, then it is recommended to delete the HPA before doing so.
