You 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.
Before you begin
You must stop the messaging engine before changing the policy.
After the messaging engine has moved, you have to restart it manually.
About this task
You might want to move a messaging engine if you are aware
of a problem that causes the server on which the messaging engine
is currently running to fail. For more information, see
Specifying a preferred server for messaging requests.
