@Joël Luijmes I can double check -- but I'm pretty sure the agent just creates the job and moves on, it doesn't monitor the flow anymore so you should be fine.

Ah you're right, the agent does check on the jobs in this case

A version update should only matter if we change the identifiers though since the agent isn't keeping track of what jobs it has created e.g.
Copy code
jobs = self.batch_client.list_namespaced_job(
namespace=self.namespace,
label_selector="<http://prefect.io/identifier|prefect.io/identifier>",
limit=20,
_continue=_continue,
)j
