Moving a messaging engine from one server to another by using the HAManager

We can move a messaging engine from one server to another by changing the policy that is bound to the messaging engine HAGroup. This is the recommended way of moving the messaging engine. You must not attempt to directly activate or deactivate the members of the HAGroup that relates to the messaging engine.

Stop the messaging engine before changing the policy. After the messaging engine has moved, we have to restart it manually.

We might want to move a messaging engine if we are aware of a problem that causes the server on which the messaging engine is currently running to fail.

See Specifying a preferred server for messaging requests.
