amazon web services - Update AWS ELB listeners from command line tools -

problem: update listeners in aws elb in transaction-like mode. i.e. delete-load-balancer-listeners followed create-load-balancer-listeners isn't good.

aws ui console allows update list of listeners (at to the lowest degree looks update), not delete+add.

is there way programmatically or aws cli?

cloudtrail logs shows aws ui console delete+create. there's no undocumented "update listeners" api call.

open questions left:

what happens if delete succeed create failed? elb should reject connections in case. what's best practices avoid downtime here? what happens existing connections?
