How to repoint SEP client in the different network zones to point to single SEP server ?

Hi All,

I'd like to simplify the Symantec Endpoint Protection Manager 12.1.3 deployment across multiple different DMZ and network zones to just one single server.

Because at the moment each network zones and each DMZ networks got its own SEPM server to distribute the policy & updates to the clients that is replicating against the main SEPM server in the internal network. I realize that this is not ideal and I wants to consolidate them all into just one single SEPM server for all of the network zones.

How to do that and where to start from ? in the DMZ zones I got approximately 130 SEP clients.
