Ansible delegate_to group

Ansible can be configured to run a task on a different host than the one that is being configured using the delegate_to key. The module will still run once for every machine, but instead of running on the target machine, it will run on the delegated host. The facts available will be the ones applicable to the current host. Here, we I used 'delegate_to' in a handler. And it worked, but with a quirk: each host delegated its own handler to my 'monitoring' host, so I got as many handler calls as I had hosts to process.

delegate_to expects an inventory host name. From your inventory, oldserver is a group name that can potentially hold several host names.

So in this case you could delegate_to: "{{ groups['oldserver'][0] }}" delegate_to expects an inventory host name. From your inventory, oldserver is a group name that can potentially hold several host names.
