Re: [Artemis] Moving all messages from one broker cluster to another

Thanks Justin, I will have a look at the import/export function. this might work for us.

AWS will not restart the EC2 instance if a process failure happens (JVM crash).
Also the backup server is in a separate Availability Zone in case the whole AZ with the master goes down.

If you have (or add, even if you don't use it) an ELB in front of the
cluster's ASG, and you configure a health check on the ELB that can only be
passed when the broker is alive, and you configure the ASG's
HealthCheckType to be "ELB", then AWS will terminate your EC2 when the
broker process stops due to the type of situation you describe.
