Planning to deploy SCOM 2016, we already have SCOM 2012 where we have a gateway server deployed for a different site say ab.com. But I do see ab.com domain is trusted and see some servers from ab.com reporting directly to management servers.
Moving to new SCOM infra, do we need to deploy gateway? as we have trust created in AD, can we have all servers in ab.com domain report directly to management server itself.
SCOM infra is in Azure private cloud and there is a ping delay of 23 ms between SCOM management servers and servers at site ab.com.
Please advise.
