How do I make my heavy forwarder, which is already configured, into a deployment server?

I have a Splunk Cloud instance and a heavy forwarder that sends in all my data into my cloud instance. I will now be installing a universal forwarder to get Windows Active Directory data in and will point my universal forwarder to my heavy forwarder. Now, my question is how do I make my heavy forwarder that is already configured into a deployment server as well? I would also like to know how do I know if my heavy forwarder is already set up as a deployment server? (I didn't set up the HF someone else did) Thanks
