This page contains details of planning and implementation of the upgrade/rollback functionality for instances in ACM-R. Rest interface users will be able to call a new endpoint in order to trigger the moving/migration of an instance from a source composition definition to a target composition definition. In this way, the migration of the instance will support both an upgrade and rollback of the instance in question. Calls to migrate the instance will take place on an instance-by-instance basis. The caller will have to supply the following parameters when making the call to upgrade an instance.
- Source Composition Definition Id - The composition that the instance is currently based on.
- Target Composition Definition Id - The composition that the instance is to be migrated to.
- Instance Id - The Id of the instance that the caller wishes to migrate.
This operation will only be possible if the source composition id, target composition id and the instance id exist in ACM.
