 1.	Go into the namespace in the portal and click on "Geo-replication".
 2.	Click on Add secondary region and select a secondary region and the corresponding Event Hubs Dedicated clusters running in that region.
 3.	Select asynchronous or synchronous replication mode as the replication consistency mode. If selecting asynchronous consistency, enter the allowable amount of time the secondary region can lag behind the primary region in minutes.

 After a secondary region is added, all of the data held in the primary namespace is replicated to the secondary. Complete replication can take a while depending on various factors with the main one being how much data is in your primary namespace. Users can observe replication progress by monitoring the lag to the secondary region.

 If doing a planned promotion, then once the promotion process is initiated, the new primary rejects any new events until failover is completed. The promotion process repoints the fully qualified domain name(FQDN) for your namespace to the selected region, complete data replication between the two regions and configure the new primary region to be active. Promotion does not require any changes to clients, and that they continue to work after the promotion event.
