I really don’t like the tone and Michis link has the answer to your question but I will try to help, too. (I understand that this isn’t the most comfortable situation for you).
The configuration of zones did not change if you followed the best-practices and documentation in the past. So update the zones config on all “agents” and satellites and ensure that the zones.conf on each node reflects the whole zones hierarchy. To make it short: It’s correct if a look at the agents zones.conf shows you the whole hierarchy incl. the master instances and all satellites in between.
Once that’s done, the endpoints will be known and your commands succeed.
