Hi, what would be the recommended setup for setting up a data pipeline where a flow run is triggered after another flow run has finished?

if you're using Prefect Cloud you could just use an automation Trigger = flow run state on whatever flow you choose entering

Completed

state Action = Run a deployment

And what would be the preferred method when I have server only (not cloud)

you could use

run_deployment

to trigger a run of a deployment at the end of the flow that should trigger the next

Thanks!
