Currently, live migration using the migrate_to and migrate_from actions is not supported for cloned resources.
If the agent supports it, we should be able to live-migrate an instance of a globally unique clone fairly straightforwardly. Anonymous instances should also be migrateable if the clone will not be active on all nodes, and one instance needs to stop while another needs to start.
Live-migrating the promoted role of a promotable will be more challenging and will likely need changes to the OCF standard, since support for the migration actions doesn't necessarily mean that the agent can migrate just the promoted role.
