In Pega Platform 7.3 and later, all nodes in Pega Cloud Services environments support associating agents with node types. With node classification, agents no longer create or utilize NodeID-based Data-Agent-Queue (DAQ) instances. After Pega Cloud Services finishes upgrading your environment, agents are mapped to the BackgroundProcessing node type by default; previously configured DAQ customizations using NodeId are removed.
At a minimum, you must review your agents and remap them to the appropriate node types and update the node type-based DAQ with any customizations; for details, see Associating agents with node types. It is a best practice to reconfigure Pega agent workloads using a job scheduler or queue processor. For more information, see Configuring resources-use job schedulers and queue processors instead of agents.
