What changed

AWS launched Agent Registry in general availability under the agent-registry namespace on 6 August. New customers must use it immediately; existing preview customers can use both namespaces until bedrock-agentcore shuts down on 17 September.

Why it matters

The migration changes endpoints, IAM, SDK and CLI clients, ARNs, API schemas, observability, and stored registry data rather than only renaming a service.

What to do

Inventory Registry references and data, migrate with dual reads or writes where needed, then verify counts, transformed records, permissions, search, approval, and rollback in every region.

Caveat

The change applies only to Agent Registry; AgentCore identity and OAuth resources deliberately remain under bedrock-agentcore, so a global text replacement would break valid policies.
