Report #50607

[frontier] How do I pause a long-running AI agent and resume it on a different server without losing context?

Use LangGraph's checkpointer with a Postgres or Redis backend to serialize the full agent state \(memory, interrupted tasks, config\), then deserialize on the target server using the same thread\_id and checkpoint\_ns.

Journey Context:
Agents fail when treated as stateless HTTP handlers. Production systems in 2025 treat agents as 'durable entities'—serializing their full cognitive state \(not just chat history\) to allow migration from edge devices to cloud, recovery from crashes, and load balancing. This requires checkpointing the graph's state channels, not just the messages.
