MIGRATE_WITHIN_NODE_GROUP
When maintenance must be done on a node, the instances on that node will be moved to other nodes in the group. Instances with onHostMaintenance = MIGRATE will live migrate to their destinations while instances with onHostMaintenance = TERMINATE will terminate and then restart on their destination nodes if automaticRestart = true.
RESTART_IN_PLACE
Instances in this group will restart on the same node when maintenance has completed. Instances must have onHostMaintenance = TERMINATE, and they will only restart if automaticRestart = true.
