Hello, not sure if I understand it correctly. But in case of DMQ, you need to have both proxies at least on the same major version (5.5.x), replication will not work from 5.4.x to 5.5.x for example. So you need to update both proxies the same time.

Because the 2 proxy servers are maintained with DMQ, Awaiting any reply for this..!
